I use my computer primarily for listening to/downloading music, occasionally doing some graphic work, browsing the internet and watching some shows (but I have my htpc connected to my personal computer since mine has a larger HDD). I used to play a lot of games, and I still get the urge to play every now and then. I have a pile of games that I "want" to play that I download over and over again and never play.
My computer is still an integral part of my life; I definitely don't think I'll be getting rid of it anytime soon. It's indispensable with regard to record and bookkeeping, storing photos, music, books, and video, editing text/making important things like CVs, but I'm having a hard time seeing its use outside of the very basic needs I feel every person has now.
In other words, my PC is really more than I need. I feel like I could do more with it, but I'm trying to get out of the house more, and I think it's hindering my growth as a person in that respect.
