I'm pursuing multiple tracks in parallel, some of which are just involved in getting the Pi integrated into my workspace. For example, every time I need to take the Pi somewhere to show it at a local geek event, test it with various other hardware and software folks have who are waiting for their Pi to arrive, etc. So, I just got an Atrix lapdock to have a very light integrated decent display, keyboard, and trackpad that can plug into the Pi with a couple of cables, which will make the Pi mobile with much less pain than the current rat's nest of cables, display, keyboard, mouse, USB hub, power bricks galore, etc., etc., etc.
I also have had to mess around keeping up with Debian kernel and library updates as I've acquired larger/faster SD cards than the ancient, slow, small card I had initially used to boot up the Pi. Then, there's the WiFi issues I've been working through, and a thousand other little things to do that would normally automagically be taken care of in a more mainstream system (even some Linux systems, such as those based on Ubuntu).
Anyway, some of my many threads (all of these being executed in my off time, mind you) are actually being executed on 3-D efforts, including Panda3D, OGLES, examples, noob tutorials, etc. It's still going to be months before we'll be able to run things as readily as is possible (but, still not truly easy to do) on full-blown OpenGL-based systems, Objective C based iOS apps, Java/Dalvik based Android apps, etc. I'm going to be busy for weeks just teasing out library dependencies, compiler flags/options, what will fit in RAM without swapping, etc., in Panda3D.
The good news is that I'm still alive and kickin', I suppose
The best things in life aren't things ... but, a Pi comes pretty darned close!
