Laptop Four tabling - Requirements?

[RacersEdge]

I'm considering this purchase as well - since I think my desktop could be in trouble. I didn't even know laptops came in 1600X1200. Any specific recommendations on actual brands/models?

Any reason to go with a desktop instead, besides price? I have a NEC flat screen 17", but not 1600 x 1200 rez. Maybe I should sell it and get a hi rez monitor.

What's the optimal setup for 4 tabling?
