Good comparison. For me the PS3 is only about first party software; Motorstorm, Ratchet and Clank, and Uncharted kick all kinds of ass. Nearly everything else is available on the 360 with increased functionality (Live, acheivements, framerates).
"The PlayStation Network, while still free, now offers most of the same features that Xbox Live users are enjoying." Sorry, but I can't seem to get a game going with a bunch of CAGs on the PS3 network. It can be difficult on Live at times, but it is usually accomplished. The Sony network does do one thing better than the Marketplace- they have (quality, not advertisments) free pics, themes, and a song or two.
Also, I think you should have included that one year later, BC is not longer emphasized. Considering the PS2 library is both vast, and has a number of great titles, this is a disappointent for Sony.
