Got my O2 Joggler now. Great device - great price for the next week or so as well.

There is a shed load of "hacking" information around for it.

If you are interested - joggler.info is a pretty good starting point.

I am going to be playing with it a bit for a while to see how far we can go with device. I already have Ubuntu Netbook Remix running - complete with touch screen, wifi etc all working! Sound needs looking at but it is pretty good so far!
