Definitely computer with a network connection. I spent a day some days ago without internet and just the television, it was then that I realized how boring the TV is.
I would say computer, because on TV you only can watch something and that's it, but with computer you can do lots of different things and even earn money, tv is waste of time
I will prefer computer of television. The reason is that for me computer can work as television but television cannot work as computer. I watch movies on T.V., and that I can also download and watch in my computer, but I cannot do my computer work in Television.
I used to be a complete tv addict in my middle school days, but after that, my focus shifted to TV. Nowadays, I even watch shows on my computer, so I have no reason to switch on my tv.
I think I could live without my television if i have a computer... don't know if I could do it the other way around!
both in general have different importance's but i'll prefer computer to television because through computer we can even gain knowledge which we can't through television.
