I don't understand why some saying: -I'll wait for Windows 7!
Windows 7 will be a new version of Vista. Microsoft won't redesign the whole O/S just to release an uphotted version of the previous one. Windows 7 will be as much resource hog as Vista, if not more. But by then, Microsoft calculates that the users hardware will carry more RAM and faster CPUs. MS have already claimed that by the release of Windows 7, the "standard" size of RAM in an average desktop computer will to 4 GB. So don't expect Win 7 to be a less black hole than Vista.
For me personally, I don't see any benefits on all the O/S hysteria lately. Vista / Win7 may be beneficial for gamers that will use all the fancy stuff on the latest graphic cards etc. But for me, all that is useless because I don't need it. My PC isn't a Gaming station nor a Game console. To me, it's just a machine for reading mail, surfing the net, download files and chat with my friends. I don't need a supercomputer just for doing that! My friend is using Linux in the same way I use Windows XP today. Looks interresting. His computer is even older than mine and still he can do all that I can do, at the same speed. Maybe I'll consider Linux later on. But for now, I stay with XP. Works great!
And if like to watch movies? -I'll use my TIVO!
If I like to listen to music? -I'll turn on my stereo!
If feel like gaming? -I'll use a game console!
(a game console is much cheaper and more powerful than my PC anyway)
Right now my life is great and I don't care about the O/S hysteria.
