I kinda like both Vista and XP. But I'd use the Ultimate version of Vista and XP Pro. There's not much you can do with the basic versions of both OSes.
My only beef with Vista is that the Cisco VPN software won't work on it! I'm still trying to find a solution or workaround, and hopefully it exists somewhere on the WWW. I'm back to using my desktop because I have XP on it which allows me to use the VPN software to connect to the company network.
