well, i got vista ultimate, and its been WAY blown up, i havent found one thing wrong with it yet, but its not on my custom its on a vista capable laptop so all driver's are fine, i have 1gb of ram (only 768 really cause the integrated graphics uses 256 of that) i can run aero nice and smooth, doesnt lag at all with 768ram, when using internet explorer 64-bit and WMP, i use roughly 80% of ram and with dual core she flies, the widgets on the side are awesome, you can download new ones from the website, anyway for those of you who were thinking of waiting for vista, if you have a manufactured pc get it now, if you dont, wait till service pack 1 comes out, that will fix all the driver issues
