couple more quick q's
Does PS3 have an onlince community like xbox? How much if it does and what exactly is sixaxis - and does the dualshock 3 have it?
It has an online community service called PSN which offers a download service (though the EU one is apalling which was being discussed in a thread last night, but you can sign up foreign ones). You can play online for free (something you can't on XBox Live) which is nice, though it lacks some of the features that makes Xbox Live so great (online messaging, account reputations, player muting, player information histories, using your own music ingame as soundtracks, achievements.
The PSN is a very good service for free though, so it is hard to complain and the only negative is seeing just how much more stuck Asia and North America get over us (something that isn't the case on Xbox Live as all stores are updated at the same time).
When you get down to equal elements however it's quite divided, where each system offers the same things, some of those are better on Xbox360 and some better on PS3.
The PS3 does not come with Dual Shock 3, instead you get a Six-Axis which, according to my Awards thread is widely being slated as the worst hardware/peripheral of the year... not good. It's an awful, awful, awful pad, probably my least favourite ever, it's so cheap and has what I'd call serious flaws (search the forums and you'll see my thoughts), however you can import a Dualshock 3 control pad from Asia for around £35-£40 each and those are apparently much better fixing one of the major flaws of the Six-Axis in regards to the analogue deadzone, so I'd really recommend you import 2 of those (if you're into multiplayer).
The PS3 offers a lot more than the Xbox360 so some will say it offers more bang for your buck, the Xbox360 offers less, but does what it does, in general, better with it's Xbox Live service, Games list, control pad (best ever) and features. The PS3 offers a brilliant media service with Blu-Ray movies, in-built wireless, a free online service (that's good) and potential for some very good games next year.
If you want a media device, then it HAS to be the Playstation 3, I feel it does all media elements better and Blu-Ray is excellent, I use mine for DVD's and Blu-Rays quite regularly and I can't really fault it.
If you want a gaming device it has to be the Xbox360 which has many exclusive AAA titles compared to the PS3's 1 AAA title (IMO of course).
Either way, whichever you will buy it will be a good console. But as of now and into next year, one is a better media device and one a better games device.
