I would carry my laptop with me on flights, but its just too big and the battery life on mine is horrible. Instead I use my Dell Axim when traveling. I havent really found it to be cumbersom, but it handles everthing I need to do when traveling. Email, Internet, Enterainment, Take notes, etc. I also like the fact that I can walk around with it in one hand while at the airport or and access all my information.
