Good thread here. I'm on the verge of springing for an ultra portable and am leaning towards Dell after looking at Lenovo and a few others like Mac, etc.
Here's the one I'm looking at:
The $1,299 model should have all the performance needed and I'll get XP on it. The Inspiron we have right now is pretty ok except it is heavy and has Vista ugh. We were going to buy a replacement desktop for the old Gateway in the office but another laptop with XP and an external drive seems better.
