Just by removing computers and video games, I'd either be a really big bookworm or I'd have found something else to pass the time. I'd have a much narrower view of the world too, as a lot of what I've learned has come from contacting people over the Internet.
I'd have a whole lot more 'simple' life, with a focus on day-to-day chores, and probably would be closer with my family and my community.
Or maybe there's something I'm missing that would make me completely different. Really technology is too big a part of my (and well, everyone's) life, so what I think it would be like is probably pretty inaccurate.
