Are there any advantages/disadvantages (besides the cost) between getting a blu-ray drive for my computer that I hook up to my TV, and getting either a blu-ray player or a PS3?
I can wait and save to get a PS3, but the power consumption and size in my already size-limited room are my two biggest concerns, which is why I considered the blu-ray drive for the PC.
only one I can think of is the obvious one -
ability to play games on the PS3
If you have the ability to get a PS3, go for it. It's the best player, plus of course you get the gaming advantage too.
As far as power consumption goes, the PS3 takes a LOT when it's on, so if you are trying to be eco-friendly and just want blu-ray get it on your computer.
If you CAN though, I would go for the PS3
