What's wrong with Windows? I love the OS, although I have used it for most of my life, so I guess this is subjective to what OS you prefer, but I still see no problems with Windows, and I use OS X a bit as well, no problems.
It is very nice! I'm curious to know if anyone here has actually used Windows, and if so...correctly. I disliked OS X before I tried it, then I found out that it wasn't as bad as I thought it was. Not sure why there's such hate on Windows, there's no need.
Yes, Apple should take some cues from Asus and provide better specs in their iMacs, totally agree with that.
