You know, the sony librie seems to have some features inherently unique to it...
It has a dictionary, albeit in japanese. It has a keyboard right there, and apparently a means of entering in text fairly easily (I tried out the dictionary function).
Shouldn't it be easy to at least replace the dictionary and add annnotation features with the use of a flash memory drive? I think I can imagine the computational and memory difficulties that lie with trying a search for word or for text, though.
Is there any project work going on to make the extra features the librie does have in order to make it more useful?
