Two Laptop questions - XP vs Vista, and 1600x1200 question

[Grisgra]

Are there any laptops that have the equivalent of 1600 x 1200 resolution? I was scooting around Dell online and was wondering whether any of the XPS systems might . . . hell, the one I was looking at has a 17" monitor . . .

Also -- any advantage to sticking with XP Professional as opposed to moving to Windows Vista? Is the latter still buggy and not worth it?
