Light as you can get AND linux friendly: that's exactly what I was looking for.
I am now the very happy owner of a sub-2 pounds, Ubuntu certified, 12.1" laptop for 6 month, and that the best notebook choice I ever made.
Right choice for me, but I am only on the road 5 to 6 days a month, so your mileage may vary if you are really a nomad worker.
