I got a PS3 for Christmas and I've spent much longer on it this year so far than the 360, much to my surprise. I wouldn't have bought one yet normally, I'd likely be waiting until the next price cut (my money is on September for that) but as it was a Christmas present I wasn't complaining.
Bottom line, I'm much more impressed with it than I thought I'd be.
Games wise, I've completed Uncharted and Ratchet&Clank, both of which I thought were very, very good. Uncharted, as someone up there said, is like Tomb Raider but good and contains some of the finest digital acting I've seen yet. The little touches, like Drake jumping for a ledge and nearly falling, grunting in pain, or looking worried as bullets ping all around him make this the closest gaming experience to an Indiana Jones film I've ever played. R&C is just lovely, lovely fun from beginning to end and everytime I put it on for a quick bash it seemed to swallow hours and hours of my time. It's short, as someone mentioned (took me about 12 hours I think) but has the usual R&C Challenge mode to encourage a second, more difficult, playthrough.
We also have SingStar, which I'm infomed is good (I'm not allowed to sing -- court order). It could cost you a fortune in DLC though. Unreal Tournament 3 I think is the PS3's must-have shooter but I'm a long time fan of the series. The mod support with all the free DLC will give this game a lifespan measured in years, and a distinct edge over the 360 version unless Microsoft pull their collective head from their collective ass. I've heard COD4 is good on the PS3 but I got it for the 360 as I have a lot more friends over there and I mostly bought it for the multiplayer.
As for the GT5P controversy, personally, it seems to be garnering a lot of hate I don't understand. Yes, it's not that long compared to a proper GT game, or Forza 2 for that matter, but I think it's plenty long enough to justify £18. I also don't seem to have this violent objection to the handling many other people have had (I am playing on Pro with all assists off) but I'm only halfway up the B series so it may get worse once I get the more powerful RWD cars. I will freely admit though to a possible case of rose tinted glasses here, because I once took two weeks off work to play GT3 with a mate (we got to 93% completion), so even the little "bong" it makes when you select things in the menus feels nostalgic.
The hardware is mostly lovely, the console feels really well made, and little things like the ability to use any memory card to backup save games, any Bluetooth headset, and any laptop hard disk are very nice. It has made me object even more to the merciless price gouging on 360 accessories. It's a peerless media centre, as others have noted, and a superb DVD/Bluray player; using it as a media player is also helped by the fact that compared to the howling tornado the 360 seems to need to cool itself it's practically silent. The pad is distinctly inferior to the 360 one -- convex triggers, WTF? -- but again, other people seem to hate it but it doesn't bother me that much.
Would I buy one yet if I hadn't gotten one as a gift? No, probably not, but I'd be getting sorely tempted now and I'd certainly cave in whenever the next price cut tips up. Do I regret getting one? Absolutey
Also: hey Owen! Nice to see you
Oh, and Grim..., the Dualshock3 does all the same motion control as the Sixaxis, with rumble as well. So no, they're not dropping the motion control.
