My brother won an 'award' from work which gave him the ability to buy anything for up to $500 on the company and he bought a PS3 as a Blu-Ray player; he has rented FEAR, bought Madden and was given NHL 2008 as a gift but those are the only games he has played on it.
Everyone I know who has bought a PS3 picked one up because of the Blu-Ray player; they have all (pretty much) stated that they would have bought an XBox 360 if they were only interested in a gaming machine. The fact is that if you're looking for a Blu-Ray/HD-DVD player and have some interest in gaming that the PS3 may be a good purchase simply because a $200 to $300 HD movie player and a $350 XBox 360 is far more expensive than a PS3.
The real risk for the PS3 long term is this rational purchase may not remain so rational for long ... The format war between HD-DVD and Blu-Ray has driven down the price of players faster than any format before, by January 1st 2009 there may be sub-$100 players on the market which would encourage people to buy seperate components.
