[maemo-developers] [maemo-developers] J2ME on Nokia 770

[From: Luis Montes]

It still would be nice to hear something from them. For all the java 
talk on this list over the last few months, I've yet to see a response 
from an @nokia email.

The screen size is definetly enough to hanlde full size swing apps, it 
just seems that we'd be limited on the amount of internal flash to store 
the jvm and full class libraries.
The average midlet is pretty small, but the midlet runner could use the 
hardware zoom buttons.

There are thousands of midlets out there, that means there's suddenly 
thousand of apps available if the 770 had the jvm to run them.
