Seriously, what does having a PS3 on launch day really going to give you? A core system with little backwards compatibility, glitches up the wazoo, and a price tag so incredible that you'd be better off putting it towards your retirement savings. Once all the launch hype dies down, you'll just be another poor slob who has paid a really high price for a really glitchy system.
Play it smart: wait a couple of years for the price to cheapen and pick the system up then. It'll be more functional, have a bigger game library, and improved backwards compatibility.

Oh, and for anyone who
has picked up the system, how durable is it? Have you all tried smacking your heads with it?
