I've got an old Xbox (not the 360, the one before) and it was okay, but I never played many games on it -- unless kids or relatives came over -- and it was a GREAT babysitter.
Unfortunately, when I last attempted to use it, the damn tray would not open (nor any video would appear on the screen). I tried every practical method I could think of without breaking it to resolve the issue, but I'm done -- it's heading to the recycling center.
Damn shame, as I have an unopened DVD remote still in clamshell for it, and unless anyone wants it (for the price of shipping) it will end up in the trash -- never opened. Hell, I've got a bunch more than that, and would send it to someone if they actually wanted it.
I also have a PS3 -- on the plus side, the wireless network is great -- no external anything required. It's all built in, and seems to work quite well considering how far away it is from the hub.
The games are also quite stunning -- very high quality (but perhaps lacking in quantity).
I mostly bought it because it is a software upgradable Blu-ray -- and it does play 1080p via HDMI quite well. However, the Sony remote (which you have to purchase separately) is actually quite lame. I guess I'm too used to how well designed the TiVo remote is (and the HD TiVo is 1080i).
I really don't see the difference between 1080i or 1080p, perhaps a very tiny, tiny bit, but whatever.
I thought about getting an Xbox 360, but I figured what would be the point.
That TiVo remote though has to be one of the best designed things ever. You don't even have to look at it to know what you're doing. It fits right in your hand, and has clues as to where everything is.
The Sony one is the opposite, you practically have to turn on the lights and study the buttons before deciding the one you decide to hit, before realizing it was the wrong one, and now you have to start or restart or fast forward into your movie.
