Query: Lots of early exuberance; maybe time for reality

There's a lot to look at with this laptop. Large screen, it's pretty, it seems to work fine. But Vista will break your heart and the graphics on this machine are not sufficient to run flight simulator (and I've got machines that seem downright scumpy and they'll run it). But it's not just hotel, road-warrior gaming. Office, all of my six-sigma stuff, just painfully slow. Oh and Sony won't even begin to talk to you about downgrading to XP. There have been any number of times where the machine just seems to lock up, a few times where the entire explorer session (files and all) go away. I'm certain this would be a great XP machine, but have no idea how to do it. Sigh. I seriously considered purchasing a Mac, and this machine makes me sorry I didn't follow my instincts.
