@DaveP1:
Actually I've been using a 'hackintosh' netbook for travelling (MSI Wind: 10" lcd, atom 1.6ghz, 2gb ram) and it's sufficient for most daily tasks (mail, browsing, IM, irc, ssh, vnc, rdp, bit of online poker, etc... most of those running at the same time.) so although I would never say 'no' to more horsepower, I've found the Atom platform adequate and quite suitable (dimension+weight) for travelling.
