Ok, so if the people knows that Vista isn't slow, Why they hate it? it's awesome!
First, I dont hate it. I use it daily and I am happy that it supports 64-bit and more RAM than XP. XP 64-bit has weak driver support.
Secondly I meant that my new very fast PC still would run XP faster than Vista in some cases. But I take this into account because now I can address more memory. It is a trade-off.
Still I am not a fanboy. I would not fall in love with Vista nor with XP. It is just a tool to do my work.
