Overall it's a good console, I voted 4/5.
Build quality, the PS3 is unmatched - it is quiet, doesn't get too hot, and looks great. The Xbox 360 simply fails in this category compared to the PS3 - it's always getting hot and is extremely loud. 5/5 here.
Extras - This is another category where the PS3 shines. I don't use Linux, so I don't know how good of a feature that is. Folding is nice and alot faster than on the PC. Blu-Ray is one of the things that really justified the cost of the PS3 to me, and it's a great feature to have. Another 5/5
Games - This is where the PS3 is weak at this point. Right now, there just aren't many good PS3 games. The only PS3 game I own right now is Resistance, and I can't see that changing until later this year. The good thing is, later this year, several good games are coming, among them Killzone 2 (hopefully this year), Heavenly Sword, and a few others. At this point, the PS3 gets a 3/5.
Price - This is the second big weak point of the PS3, it is a very expensive console at $600. The thing that makes this justifiable in my mind is that it is an excellent Blu-Ray player as well, and with a Blu-Ray player costing something like $500, suddenly paying $600 for a game console that is one of the best Blu-Ray players out there doesn't seem so bad. The good thing is, Sony should be able to really cut costs as the Blu-Ray drive drops in price and they are able to move to 65nm on the CPU (which they are already doing, I've heard).
