I'm interested in an ultra small, lightweight laptop, a pound or under for my two week travelling and non stop security checkpoints. I don't mind the tiny size since that is one of the priorities for me (I can type fine with it) and need the clamshell design. I already have a desktop, regular size laptop and netbook for shorter trips. Does anyone have one or can recommend which manufacturer? Umid has one, but there's no where around here to test it out. I liked the 1.5 lb Sony P, but the even smaller machines are more enticing to me now. I have my phone for basic internet, but I need a laptop to run specific programs.
