Computing... (no, I didn't say that)... Boating, Music, TV, Satellite, Telecoms, Technical / Mechanical things.
Friends etc...
Trance, House, Classical, err, anything really but heavy metal and opera.
Sci-Fi, Action, Comedy to name a few, but I'll watch just about anything really.
Stargate, Star Trek, Big Brother, Discovery Channel.
I don't read much more than instruction manuals and boating/computing mags :(
