Well it isnt better than XP. It is still in Beta. There are many apps that still dont work with it. I haevnt found a Anti Virus to install. Nor have i gotten a firewall to install. Games dont work. And WMP11 is buggy and crashes.
Plus you have to be invited by M$ to get beyond the 14 day trial. If not any serial you use wont activate and the OS will stop working in 14 days.
