I have to say, my iPhone is something of a hobby: Finding new and useful apps... will definitely have to resurrect that old "recommend an app" thread, here for more input.

Aside from that, not enough time with PL, follow the games industry is definitely a hobby I really enjoy though I play very few games anymore, learning programming is a hobby turning into work(!) and reading any sort of book. I'm a big, big fan of world cinema, The last movie I saw was, El Secretos de Sus Ojos The Secret in Their Eyes which won best Oscar for Foreign film. Enjoy running and play a few team games, as well as referee duties, despite the abuse!
