PS3 not getting highest marks
There is one flaw with the PS3 playing films.
Because of the sheer power, size and activity of the machine it generates quite a few watts on heat, all of which need to be removed. Now, when I was working at EA the PS3s were all actually rather loud, now while this doesn't really affect gaming, I can imagine hearing that whine of the fan while watching, for instance a quiet crime thriller, maybe off putting. However, the development PS3 kits we had would also "spin down" when they weren't actually being used much, which I hope is a feature of the retail boxes (as I'll be ordering one very soon).
With standalone BD-players I see the need for a wifi connection as more important than with the PS3... afterall the people who are happy to have cables running the building (or already have cables running the building) are more likely to want a games console.
With myself retiring from high-end PC gaming (what with the rebranding of games as HD, as if my 1600x1200 PC wasn't high enough definition) and the (what I think) disaster of Vista, the PS3 is one hell of a bargain.
