Welcome to the new switcher
Steven has switched - congratulations!
Eight monts after my own switch, I can't thing of any serious negative points. I'm waiting on oqo or Antelope to come up with actual products so that I can complete my mobile (and only) setup with a mini-PC for mobile cross-platform development.
Currently I use VirtualPC (recently bought by you-know-who) when I need to test PC stuff while on the go. It is workable but fairly slow, which is understandable given the processor emulation that is required.
