Rather than going through your whole post, I'll just make some quick comments.
1st of all, hearing that you prefer the PS3 library shows you're likely out of touch with the general sentiment. I mean, of course everyone has their own tastes and preferences, but you only need to look at the number of top games by review score across the platforms to see where the "top games" are. Again, not digging on your tastes - you obviously got the best machine for you - but it's hard to disagree with pretty much all reviews of all games, with the 360 clearly on top. This is of course also reflected in the massive game sales on the 360.
Hearing you still play Resistance weekly too is great - but you can't honestly say that a person looking for an online shooter is better off passing up a 360 + Halo3 for a PS3 and Resistance. Again, look at reviews saying it is the best game on consoles for online shooters. Sure, Halo might not be to your tastes, but a majority of gamers are not in the same mindset as you - and this is reflected in both better review scores, more people online, and better sales.
Seeing you quote LBP and PS-Eye (and the comical
Eye of Judgement) as reasons to buy the console are a little strange to me. Maybe it's just because there's little to no interest there for me, but I can't help but see these "initiatives" as being a little behind the eight-ball. The Eye-toy type games aren't really going to move to many consoles in my eye - that audience is the Wii/DS audience. As for LBP, there's certainly potential, but it's a 2008 title whose flag is simply "user generated content". I can't see a mass proportion of gamers walking into a store at Xmas saying "I really want a PS3 so I can build a 2D platforming game level sometime next year!"
As for the Apple analogy, I completely agree - I think both MS and Sony missed the boat compeletely here, while Nintendo seem to be sailing into the sunset.
