I need 64bit Windows with my 4gigs of ram (and another gig on my graphic card
But really, there's no reason to avoid the 64-bit version. It's the future. If anyone's worried about compatibility, I can tell you it's not a problem anymore. Unless you have some pesky apps installed that you use for work (yeah, there can be problems... especially if they're bloated and require a ****-load of drivers to run) or an ancient printer, I wouldn't worry. 64-bit drivers are available nowadays for pretty much every device that's less than 2 years old. So, if you have a new PC, 64-bit is the way to go, IMO.
Also, does anyone miss XP's status bar functionality in Win7 (and Vista also)? It displayed some useful information like how much free disc space you have left and the size of all files within the folder you're in. I miss this quite a bit, and I see no logical reason why M$ removed it.
