I would be happy if they decided to go the PDA way.
One thing I would really like is a stable Linux PDA, with just wlan and/or bluetooth (nowadays chips that do both are cheap enough). Even video acceleration is not that important for me (it would be nice, though).
There are all those HP and others PDAs that can run Linux, but let's face it, when one model fully works you can't buy it anymore unless on eBay like sites.
I can't start developing software for a Linux PDA if when the software is finally done and tested I can't buy any more the PDA where it was tested.
