I have yet to find any letigimate complaints for Vista. I turned off prefetch and scaled down Vista to an XP style (while still leaving Aero on) and I found it used the same or even less ram the XP. Of course I turned back on prefetch and it's ram usage went sky high, then again, so did the speed over XP.
I game on Vista, run VM's with VMWare Server, and design graphics and webpages. I can run Vista Ultimate, Battlefield 2, Windows 2000 pro VM image, and Macromedia Fireworks MX all on 2GB of RAM all at the same time. I could never dream of doing that on XP because XP had such horrid memory leaks and memory management.
I'm seeing more and more that it is people not wanting to devote any brain power to learning to use a new OS. Vista is great, but if you're moving from a lesser OS, it does have a learning curve. Stop running from change and staying in your little comfort box.
Haha i actually got negative rep being called stupid and such for liking Vista. Is that because it's now 1337 to hate Microsoft? Whoever did that negative rep, you have no life, no brains, and apparently no genitalia since you were afraid to post your name with your rep.
