I love some of the features, but I already pay monthly for my 360, it was here first and has been a good machine, I don't see myself replacing that experience with this one (largely due to that's what all my friends play, I havent been successful in getting others to get a PS3) OR paying for a 2nd console's 'premium' offerings.
The 360 got many of us accustomed to paying for some of this stuff, and the PS3 now doing it will just get us accustomed to choosing one over the other with our wallet.
Doing this 3 years after launch also looks more like a money grab than anything, this would have all been OK if it were like this at launch... but it's been pretty clear for a while they were out-innovated by the 360's online experience. Now they're working on a better Wii controller for the PS3, while MS goes the way of innovation with Natal (unproven, so TBD how that pans out). At some point Sony will stop copying and innovate themselves (cloud saves is cool, but it's also already done on the PC over Steam).
