Guys... I need convincing. As a regular XP user, can someone perhaps lay out the sales pitch groundwork to convince me to buy Windows Vista. Amazon.ca has all of the versions priced. I see Home Premium for 299.99. I suppose that is reasonable. My system is a couple years old: 3.2 ghz P4, 1 gb ram, ati 1600Pro 512 mb AGP. I havent loaded any betas.. perhaps I should start with the public issue. But in terms of shelling out the 3 and a half bills, where does Vista go where XP does not? Interface improvements I can already see, but functionality wise? Also, what version is best for a more than average home user. I am guessing Premium.
