I have a Wii, DS, Xbox, Xbox360, PSP, PS2, and PS3.
I love my PS3. Most of the debate I’ve heard involving the PS3 has been about the price when held up against the XBox360. IMO it’s honestly worth it to get the PS3.
Heres a breakdown of how the prices vs features work.
The two main things I like over the 360 are the PSN (Playstation Network) for the game & movie downloads, and the lack of chance in getting a RRoD.
