Something I'd advise to everyone, a USB vacuum cleaner. You think they are just stupid prehiperals, but they are actually really useful. I got mine as a kinda mini joke gift at christmas, but I actually use it more than any other Xmas gift I got- use it to clean my laptop (keyboard, screen edges, inputs etc), my PC (same), but also much more.

Ever tried cleaning a guitar bridge? Crap gets caught all in them and unless you take every part of it off you can't clean it. With my mini vacuum I can clean any part of my guitar without even removing the strings, but theres more! I clean my phone, webcam, anything small and fiddly to clean. The mini vacuum also has 3 different heads- a brush, a thin slot tube and a standard small tube- so useful for everything!
