Looking at the webOS internals stuff I see I could get pretty much all the command line stuff I want

App development is a bit limited to either C or Javascript. It does have SDL so maybe pygame could work on it. Also I think I saw someone post that they are shipping qt so I wonder if that'll become a possibility.

The two main issues are (1) limited HW availability due to single vendor and (2) with large parts not being open and HP limited SW upgrades, will we run into a similar situation as we do with Nokia and some Android manufacturers that to upgrade SW you have to buy a new device.
