of Symbian and the fact that Nokia just signed a deal with the software devil to use Windows on their handsets, I think there is a huge opportunity for Redhat to go after the mobile device market.

Seriously if you want ARM tablet support in Fedora build a Fedora for ARM tablet (or at least a tablet of choice as you'll probably need a lot of one off driver/kernel bits and customisation per board).
The Debian folks run on one of the tablets already.
