Re: J2ME on Nokia 770

Hi,
     Well the Nokia maemo team won't care until they get a product=20
program that requires Java (that's my hunch :-)

Yes, there is no reason they wouldn't do it, and we all await Nokia=20
Maemo's coming to Java. They might be waiting for the community to put=20
up all the basic work in the mean-time though...

It all depends whether they go for MIDP or OSGI, or both. OSGI requires=20
CDC, whereas MIDP only requires CLDC. But with such a screen size (and=20
probably future ones as well), they can do much better than just MIDP.

Then there is also the enabling of Hildon apps dev in Java.
