I'd recommend JKDefrag as a good defragmenting application. Worked great on my old computer that ran Whendoze and others that I've worked on. Microsoft stopped making the Defragmenter work properly after Windows 2000, so if you want to do it right (like most other things on the OS), you'll have to get a third party application to do it. Which is ironic, since defragmenting is
supposed to be the answer to issues in Microsoft's FAT and New Technology File Systems that causes Windows to just throw files wherever it wants in discs it's saving to, rather than keeping everything together. That's part of the the cause of the slowing in the operating system over time._________________________________________________Also, more and more game developers are developing games for Mac OS X, or both systems, including:
Electronic Arts,
Blizzard,
Feral Interactive,
id Software,
Ubisoft,
LucasArts,
Aspyr Media,
CCP Games,
TransGaming, Inc., among many others. So, as you can see, finding good games, even from the big name developers, isn't really that hard for us Mac users.
As for non-gaming applications, it's extremely easy to find a Mac OS X equivalent of pretty much any application. Plus, there's sites like
Wakoopa,
VersionTracker, and
Apple's own applications section to make finding them even easier. Anything you can do in Whendoze, you can do in OS X, only faster and easier. You can even run most Windows applications in OS X, if you use
WINE. And, yes, that includes many developed-for-Whendoze games.
I could list a bunch of features about OS X, but I'm a bit too lazy for that right now. =p
