I'm fairly new to the N800 scene, but have used Linux/Unix in my professional life for about 8 years now. One place where I've been weak is that I don't know ANY programming languages. I'm looking to overcome that shortfall now by learning something, however I feel overwelmed by the options that are out there.

Since I have a number of ideas for applications I'd like to see on the N8x0 and I presume any language that would work on the N8x0 would also work on the PC what is the best beginner language that the tablets support that people get a lot of use out of? And if you can please recommend resources for learning (web pages, books, etc.)
