Well I think you need to do some research as you'll struggle just to get a Blu-ray DVD player for that money.
On the subject of companies losing money on the consoles. They all lose money on these things for a couple of years but they will make a nice profit off them in the long run. Otherwise there is no point in doing it, it doesn't make sense. Sony aren't out there to give us a bargain they are out there to make money. That's the only way to survive, not give things away.
Lots of people buy the consoles to sell onto desperate parents who are in a desperate rush to please their child and don't mind paying a few hundred £s more if it gets Xmas sorted out .
