For what? I have absolutely zero reason to own one but for giving my consoles connectivity, which I haven't really cared about up until pretty much yesterday. I've never had more than one PC, and never really had a laptop at the same time as a functioning desktop (except once, and I had no need to hook the laptop to the net).
Anyway, to expand on what I said earlier... yeah, I'm digging the PS3. I always kind of assumed that it would be nicer than the 360 in general, and that I'd probably like using it better, but the price and lack of games made that entirely irrelevant. Since the price became a non-issue, the lack of games was no longer a big thing since I expect the library to increase and there are a number of cross-platform titles that I'd give the nod to the PS3 versus the 360 if I had the option. Plus it's nice to know that if my 360 ever dies, which seems all but inevitable at this point with things being as they are, I'll still have a console to play.
To answer your other question, Cobra, I don't have an HDTV yet. Still just playing on the old TV. So far that's been relatively fine, with caveats. Folklore plays, but instead of a nice letterboxed display or an intelligent change in display method, it just squashes the widescreen and makes everything look like ass. I'll be waiting to play that one. Burnout Paradise fairs much better. It's a little hard to read some text, and I get the impression that I'd be able to see distant objects a good deal better if I had a better TV running at higher resolution, but the game is perfectly playable. Uncharted seems to generally be the best of the bunch, as it suffers no issues whatsoever from being on a standard TV and still looks flabbergastingly good. I'm very much looking forward to the new TV, but I feel no particular urgency for it.
