I was told by my friend that you can now pre-order Windows 7 upgrade "Home Edition" from Best Buy for 50 dollars. This seems like a damn good deal for a Windows operating system. Right now I am dual-booting Windows XP with Mac OS X Leopard on a Penryn MacBook Pro. I plan on upgrading to Leopard once it comes out, and maybe Windows 7, but I am not sure if it is worth the money over XP or Vista. I bought Windows Vista Home Premium Edition about two years ago, installed it, and it worked decent. The only problems I really had with it was I didn't like the new UI, it wasn't slow, but it wasn't fast either, and it didn't run a lot of old games I enjoyed. So I erased it and installed XP and haven't looked back. I actually prefer XP's default blue UI over the new, corny stuff. If I had it my way, Windows would still be using the Windows 2000 UI. -What advantages does Windows 7 have over XP and Vista? -How comparable in speed is it to Windows XP and Vista in gaming and everyday use? -Is it possible to install older UIs onto 7? -Should I get 64-bit or 32-bit? -Can I upgrade from XP to Windows 7? Thank you.
