Ubuntu in your Pocket with good Keyboard?

Hi,

I am looking for a pocket size device that would fit into my pocket, with Ubuntu and that would have a keyboard to type.

A not too small keyboard would be desired.

Would you recommend me some devices ?

thank you very much !

The Pandora handheld looks pretty ok:
