The computer I'm using now was built specifically for gaming. Apart from that, I also use this PC to shop online for hardware. I rarely use it for anything else, except maybe to visit Techspot and two other sites: a muscians' website and site dedicated to Hemingway readers.
I use a laptop for work-related tasks, research and sundry communications. I have a copy of MS Office installed in that laptop. For now, I have Windows 7 on it, but will be switching to W8 soon.
I'm not much into the internet, I think, and am becoming less and less so these days. I am not a member of any online social network. I do not have a Facebook account, or Twitter, or whatnot. I will play online once or twice a month, maybe.
That's about it.
