I always wanted to play Ico, I could've picked it up for $10 at one point! Now the game appears to have appreciated in value, I heard it tanked when it was in stores, I missed out!
360 has more games, PS3 is more or less suited for an HDTV, it's a really good system PSN is free and MGS4 is really awesome! Though 360 usually gets more exclusives and killer apps. Both systems are about the same in the visual department. Though 360 accessories tend to be a little cheaper, they're both good systems with their own pros and cons.
Thanks for the recommendation Fuzzle King that'll be a good place to ask, I think the general rules apply when taking care of game systems though. I have a microfiber cloth which works really well for removing dust from the surface, sometimes I vacuum out the vents, and I make sure it has plenty of space around it because PS3 gets really hot!
