Its like saying, I'm going to stop using HP and use a Dell. Theres no difference in user experience, just who you give your money too.
[edited grammar]
I couldn't disagree more! There is a huge difference in user experience. I had been a PC user (DOS -> Windows) since there were 386's (8MHz) and bought a PowerBook in May of '05 and have hardly used Windows for personal use since (I have to admit XP runs very well on a corporately controlled and managed machine) ... and when I have to use Windows its to fix my wife's problems! (she's even sick of all the junk).
In my opinion, Windows has a few major things wrong with it:
1) the registry
2) installing and uninstalling programs
3) DLL dependency
4) programs need to be confined to a single folder (ex. an app icon)
Listen, OS X is great because it doesn't have any of those problems. If you want to try out all the software in the world you
may have to install 5% of it. Dmg's are great because if you don't want the app you just unmount it and trash the dmg, no uninstalling and no cleaning up what it left behind (except for the occasional preference file [but there's even an app that'll do that, AppZapper]).
Of course OS X needs a slightly better File Manager but if it went as far as Windows Explorer does it would be overkill (PathFinder). You have to remember that OS X does a lot of the file management itself. So if you are willing to adopt its system (which is extremely logical anyway) you'll be a lot happier. iTunes manages the music, iPhoto manages pictures and the Finder does everything else.
Most people who don't like OS X don't like it because they like to maintain control of every aspect of the OS including the file management. Personally, I hate file management and am very happy that OS X does a great job of it. Also, having weak right click options really isn't that big of a deal in OS X because its designed more with hotkeys (shortcuts) in mind (command this and comd+shift+that).
All-in-all, OS X is a very intuitive Operating System that is built upon a very stable core (Berkley's Unix). As others have said, system stability only comes into question right now because Apple just switched to new hardware and to new code (Universal Binary). I have PPC OS X and it has never frozen on me. I've got a perpetual beach ball before (like the hourglass) but was able to either Force Quit the affected application or do the dreaded restart (you'll hardly ever have to), and I've never seen a kernel panic (akin to the BSOD).
I think you'll love OS X if you can move away from the Windows way of doing things and let OS X manage itself. Just use apps and OS X the way it was intended and you're straight.
Since I've switched
I use my computer less and am far more productive.
ps. other great things to note are brilliant system wide spell checking (as I type this), the dictionary and expose.
