Now I need Vista to fly away

Cool, just received today the brand new Microsoft Flight Simulator X! Now for me it's  the first time I see in an official documentation that Vista is recommended for the best flying experience of your life.

I am running FS X on XP at the moment, and so far it's quite cool. Be aware, FS X require 15Gb of hard drive space! So the installation, even flawless, take about 45 minutes on a good desktop PC.

Now I need to have a new faster machine and Vista, probably in two or three months
