So I'm on to new stomping grounds at Canonical now, working on the Mobile team. One of the things we work on is Ubuntu Netbook Remix. If you have a netbook, check it out. You can even run it straight off a USB stick to try it out first.
The other major thing we're working on right now is the ARM port of Ubuntu. Lots of cool stuff going on here too. Jaunty went out with support for iMX51 boards, and even more great ARM stuff coming for the next release. Stay tuned, lots of fun stuff coming with this.
