As soon as I expect to be doing actual work, I bring my 13 inch macbook. A netbook still requires some sort of backpack or bag; at that point I can carry a real (full-size) laptop. Comparing this with my last laptop (bought 5 years ago), it was a total pain to carry around. Back then, a netbook would have been good. Nowadays, if I ever planned to be without a laptop, a smartphone would be the next size down for me, as it's the biggest thing I can fit in my pocket.
