Free online play would be great, and I hope that one day Microsoft wakes up and gets with that program. I already use rechargable batteries, already have a blu-ray player, don't care for streaming videos from my PC (it already has HDMI output), and my router is a whopping two feet from my entertainment console. It really boils down to the exclusives, which isn't many that I want to play.
I can't wait to play MGS4 and God of War 3, but $400 is still too much. I've already set the value at $300, and if the PS3 ever gets that low I'll buy one.
I hear ya man, I hear ya. Just wait for the price cut. It's almost a guarantee that they'll HAVE to cut it down before or during the holiday. Rumor is they might have one around the new Madden release. Trust me, it's worth the money, but a lower price would be sweeter, especially those like you who want the system but believe it's too expensive.
On the side note, MS did do one thing right with the hardware, which they offered a cheaper barebones alternative for those who just want the system but not pay an arm and a leg for it. Sony had a similar idea when they first launched but it's really the hardware inside that drives up the price. If they could dratically make the cell processor cheaper to manufacture, they could sell these roughly the same as a 360 pro.
