That's a great looking machine, and the specs are awesome, but I refuse to buy Sony Vaio. They have some of the worst driver support ever, supporting the exact version of Windows shipped and nothing else, ever. Forget about Linux support, it doesn't exist. Forget about even supporting future service packs of the Windows release.
When Windows 7 SP1 comes out and Sony refuses to update your drivers, enjoy your $3,000 paperweight. Been there, done that, refuse to buy a Vaio ever again.
