Perfect Multi-tasking
So far, I've described OS X's multi-tasking as very similar to what is currently available under Windows, but where OS X sets itself apart is in a little feature called Exposé (note that typing an accented "e" is extremely easy under OS X - ALT-e followed by the "e" key or any vowel will do just that).By default, Exposé is activated by one of three function keys - F9, F10 or F11. Each function key serves a different purpose, each of which is a feature of Exposé. The theory behind Exposé is simple: it is a way of getting to a specific window on your desktop as fast as possible.
We start with our cluttered desktop...

Hitting F9, for example, will cause Exposé to zoom out all of your active visible (unhidden) windows and essentially, tile them across your desktop. Then, using either the keyboard or the mouse, you can select the window that you want and everything goes back to normal, with the window that you have selected appearing in the foreground. The rest of the windows are untouched and are all in their original positions. The window that you selected is also in its original position; it is simply moved to the front so that you can see it.
Hitting F9 activates Exposé across all applications.

If you don't want to Exposé all windows, you can just Exposé the windows within a particular application (F10 by default), which is extremely handy for dealing with tons of images in Photoshop for example.
Hitting F10 activates Exposé across only a single application's windows.

Another example of Exposé's usefulness in editing all of the images for this article in Photoshop.

The final Exposé function lets you view your desktop (F11), which, to me, was like a more polished version of Windows-D, since after I was done doing whatever it is I needed to do on the desktop, Exposé deactivated and my screen was restored to its original state.
Hitting F11 reveals the desktop.

The beauty of Exposé is difficult to convey in text alone. Honestly, the best way to evaluate it and understand its potential is to use it - luckily, there are Apple stores for this very purpose. Keep in mind that Exposé is very customizable as well and the three function keys that I mentioned above, although the defaults, are not the only ways that you can configure OS X to activate Exposé.
The benefits of Exposé are numerous. If you ever feel overwhelmed by having too many windows open, Exposé definitely alleviates that feeling as you don't have to tab through multiple applications to finally get to the window that you want. While Exposé does make having only a single display better, heavy multi-taskers will still enjoy the benefits of a dual display setup.
Since the OS X desktop environment is completely OpenGL accelerated, the performance of features like Exposé are not CPU limited - instead, they are GPU limited. Luckily, using Exposé with many windows open is not very stressful on even a Radeon 9600, but you do run out of video memory very quickly - in which case, your system ends up swapping to main memory over the AGP bus, making the Exposé animation considerably choppy. It seems that the sweet spot for more than a handful of windows open is around 128MB of video memory, with 256MB being perfect - needless to say, I found the mere 64MB that came on the Radeon 9600 which shipped with the system to be too little. There is no detriment to functionality if you don't have enough video memory; the Exposé animation simply becomes more choppy (which can be annoying on a $3000 system).

If you are having difficulty maintaining your Gf's mac you must be doing something wrong. You CAN use just about any non apple hardware for it. Most if not all wireless devices are Mac compatible. Most PCI Cards I've used are just plug and play on the Mac so I'm nost sure why you are having such problems.As for this article I find it prett well balanced.

I just recently showed an eMac user (and his unit was an older 800MHz one, not the current 1.25GHz G4 model) how to turn his edited home videos into a DVD. At home I run OS X 10.3.5 on a G4 tower that's only 400MHz, with a 16MB ATI Rage128, and it's still fine for what I do (Photoshop retouching, a bit of video editing). I also have a 2.4GHz P4 Dell PowerEdge server for testing Win2K3 Enterprise. The Mac has no antivirus software; neither does the Dell -- but the Dell is fully patched, and I don't run IE on it except for Windows updates.
You also wrote: In an office environment, I cant think of anything that a mac can bring to the table that would offset the huge cost associated with each machine when compared to a windows machine that is suitable for the same task.
I respectfully beg to differ.
Re: "I can't think of anything" -- perhaps you might want to try thinking "outside the box" (literally). I derive part of my income from defending corporate Windows networks from malware. The billable hours required to do this are not at all trivial, given the increasing cooperation between spammers and virus writers -- blended threats are now the norm, not the exception. You can literally plug a modern Mac directly into the Internet (cable, DSL, whatever) and it will be fine. OTOH, I have plenty of experience with unprotected and misconfigured PCs in home and business settings, that were taken over by various kinds of nasty malware.
Even Bill Gates' own home PCs were hit (see ZDNet news story linked in an earlier post), so the Chief Software Architect of Microsoft has declared that MS will do something about it.
I recall a recent incident at a home building company, where I support the Macs in the marketing department. While the rest of the company was offline due to a worm that had gotten onto the corporate network from a laptop that carried the infection from home, the Mac users just kept working away, undisturbed by the support tech who was dashing madly from one PC to another to load a scan and remove tool -- and I had done exactly the same thing weeks earlier at another, all-Windows office. In short, we should not just look at hardware cost, look at the TCO (total cost of ownership). At C$95/hour for tech support, any price delta between Mac and PC hardware in an office-type environment can be quickly eroded by just one piece of malware running loose behind the defense perimeter. Since there are currently ZERO viruses for MacOS X, antivirus software and tech support to deal with malware intrusions are variable costs a business running on Macs does not have to deal with. Also, see my earlier post about the ratio of support techs to machines -- 1:208 for Macs, 1:70 for PCs, and this is based on my experience in large companies. Do the math. The costs for the "cheaper" PC quickly add up. I say this as someone who has worked in large PC companies (IBM, DEC, Compaq, Fujitsu) for much of his career.

I think the whole pre-emptive multitasking thing may be a case of confusing the definitions or concepts in an attempt to explain why both Windows 9x/ME and OS 9 and earlier all could be crashed very easily by improperly written applications, while Windows NT/2000/XP and OS X are much more resilent. While I am not so sure of the proper terminology myself, I _thought_ the problems came from lack of (or improper implementation of?) protected memory, rather than inability to multitask.fxparis - Monday, October 11, 2004 - link
victorpanlilio wrote in 135 (among interesting precisions) that our Macs are " inherently more secure than Window "I just " fear " that those leeches dedicated to hassle other people work and life have many skills and adaptation potentiality when it comes to "mal-programming"
I hope HE is right and I am wrong

Err, oops, sorry 'bout that.Actually 9x does have pre-emtive multitasking, and it's dead easy to prove. Write a program like this:
int main(void)
{
while (1==1)
{
}
return 1;
}
Under a non-preemtive system, such as Windows 3 or earlier, this will hang the system. Running such a program under windows 9x will just result in a hung program (obviously) but the system will still be fine. On a Cray, of course, the application will finish running in under two seconds ;)
I have no idea why MS says 9x doesn't pre-emtively multitask, except possibly to try to convince people to upgrade to a NT-kerneled OS (which had pre-emtive multitasking from the beginning).

So basically, the cheapest mac you can buy, that runs osx decently, costs 1300 dollars. What about the majority of people who dont have that much money to spend on a computer? Apple gives them no other option. I would not consider 1400 a decent price, especially in a corporate environment, where $800 workstations are more than enough for almost any sort of office work. In an office environment, I cant think of anything that a mac can bring to the table that would offset the huge cost associated with each machine when compared to a windows machine that is suitable for the same task.mxzrider - Monday, October 11, 2004 - link
i have both mac and pc (pc has windows and mandrake) i can live with out either. i use my mac (ppc g4) for video editing, but i am getting in premier, media 100 8 is getting really old. so i might sell my mac cuz it is dirt slow compared to my 800$ pc. i got hte g4 right before the g5 came out.(piss me off). but i can type faster the the apple can keep up. so i might go in to my 5 year old cusins room. or sell it for 1500 and get a new pc. i have floated farther and farther away from mac.Maybe becuase i dont do as much video editing much any more.victorpanlilio - Sunday, October 10, 2004 - link
GoodWatch wrote in #134: I’m just waiting for the first port of OS X to the Intel platform*sigh* Don't. Apple still makes most of its income from selling HW, not SW, and though it could be argued tongue in cheek that Macs are just expensive dongles for some really world-class apps, MacOS X is optimized for the PPC architecture -- even though its Darwin OS core is synced with an x86 version, OS X on x86 will likely not be sold to the public as long as Steve Jobs is CEO of Apple. Just imagine the developer revolt that would ensue.

Being a PC only ( well, OK, Debian Linux too ) user for the past 7 years I always heard the MacHeads claim a superior system. I admit to really wanting a Mac in addition to my PC.Luckily I won a Mac G5 with a 23" Cinema Display this past May! I was thrilled to say the least. I have been impressed. Why? Being a "computer guy" I am always getting nagged by friends and family to help with their PC woes. I have been overwhelmed lately with the endless spyware, adware and browser hijacks occuring with Windows machines. A lot of the help is for elderly people who have made the jump to computing. I admire them for this. However, it is an absolute jungle for these people. IE6 is a dog now infested with fleas and ticks. These people have given up surfing the web because of this. Firefox and Mozilla help but, compared with Macs, PC's are a a bitch to surf with lately if you don't have the know how.
I have taken to suggesting people buy Macs now for this reason alone. iLife is a very simple and easy to master suite that does all they need to do. Safari, IMO is a pleasant surprise.
Bottom line? Macs make it easier to work and play rather than be under the hood all the time scanning for spyware etc;.
This was a good article but, I found it to be nitpicking. Everyone, and I mean EVERYONE who comes over to my house and tries the Mac wants one now. I do web desing and graphics work on my PC. I am accustomed to it.
I think it's a smart thing to learn all the OS'es you can! I use Linux, OSX and XP on a daily basis. I am teaching my kids all 3 too ( as well as BeOS!! ). Truthfully, I wish Macs were less expensive. They are very nice machines and the OS is stellar and less prone to Windows assaults which, lately, is becoming a HUGE hassle akin to an epidemic.
The correct answer is that Windows and Macs are both great. However, Windows seems to be asleep lately with regards to security.
