RIM's been trying pretty hard to build a popular smartphone (in today's market) without much success. I'm not sure having their phone's "Facebookized" would make them that much more popular - and it would almost certainly not be popular with their remaining enterprise base. Not to mention that my sense of the cultures of these two companies (admittedly, from the outside only) is that they're about as oil-and-water as you can get. Buying RIM would mean taking on maybe a billion or more in inventory risk, plus the risk that you'd see a lot of the talent walk out the door anyway (something that's been going on for a while now.)
