I got my PS3 because it doesn't sound like a hoover, ala 360 - it also, to me, has much better media functions now that avi files can be played*.
Whilst the online part of PS3 sucks hard, in comparison to Live, I expect that it can and will be fix if/when Home comes out.
Either way, I’m happy with both, the PS3 gets the most use now though.
Scort.
* I expect 360 can also play these, but see the hoover comment.
