Hey and welcome

I'm another male omnivore, I'm sorry :P

Just wanted to mention a couple of things... since you said your tablet filled up with applications quickly, you might want to look into cloning your operating system to your internal memory to give you more space, see this thread: http://www.internettablettalk.com/fo...ad.php?t=19639

Also... sort of a self-plug but I and another guy mentioned some resources for getting started programming with Python on the tablet, which is by far the easiest language to get started with, here: http://www.internettablettalk.com/forums/showthread.php?t=22066

For java... I think Jalimo is a fairly standard implementation of J2SE1.5 so any java docs should apply to that, except for swing libraries. Swing support isn't "official" on the Maemo platform but you can get it by installing gnu-classpath
Oh, the other thing that I should mention is there's no java compiler available for the device, so I usually use the JXXX compiler service. (it's an free online java compiler)
