I know this isn't something on your guidelines, but do you like the outdoors? If you do, I definitely recommend getting this It's a stove that you can recharge your phone, GPS, or any electronic that can charge via USB.

If you like music, what about a nice set of headphones? I just got a set of them and I love them. The music quality is excellent -- a lot of professionals use them to do recording and mastering, and I know for a fact that Hans Zimmer has a pair of them in his studio. Definitely better than Bose or Beats by Dre (ugh).
