I recently 'switched' back to Windows after five years using osx 10 and so far I like it. I think Windows VISTA is better than mac osx 10.5 even. Really. I'm not making it up. I don't understand what the fuss is about regarding VISTA -- I've had no problems with it (yet). The thing is it seems to be faster! I think because the system isn't bogged down rendering all this eye candy, like it is under OSX 10.5. I mean the fonts and icons are huge under OSX 10.5 by comparison to VISTA. And I didn't realize how glad I'd be to see that rediculous bouncing dock go away. And the shortcuts. How I've missed those Windows shortcuts. - from a former 'swticher' who has 'switched' back.
