Weight and size are not really a concern for me. Screen space and power are.
Sager has dual channel ram which no other laptop maker has.

A "12 pound notebook" and "easy to pick up" shouldn't be used in the same sentenceQuote from spyderman:
It is still easier to pick up 10 or 12 lbs in a folded case than a screen, computer, wiring.

Quote from ArchAngel:
If you really need a high rez screen when you're parked somewhere, toss an LCD panel into a PC bag - external monitor resolution goes up to 2048x1536.
A full blown (but very heavy) 3GHz P4 portable desktop like the Sager is a more raw horsepower package (at the expense of 5 times the weight), but how much raw CPU do you need for trading?
Quote from hardrightedge:
I run my Sager 12 lb monster 16 hours a day at home and it hasn't rebooted in the 4 months I've had it. It worthless on airplanes but I wanted something for a hotel room and its like taking your desktop. The fan is noisy on a 3.06 because it variable, and kicks on and off all day.
I'd also look into resellers rather than Sager's own site.
Here's a great Sager forum:
