I don't get the big fuss over BBM. It's nothing more than proprietary threaded texting app - specifically for one phone manufacturer. That's all. It does nothing that a vanilla droid messaging app doesn't do. Oh wait, it will PING! a user. Whoo hoo. Standard msgs notification works just as well without the catchy name...
You can send video in a number of ways with Android. Regular old txt/mms works great, and it also threads and keeps it organized (just like BBM). Upload to FB. Email. I don't understand why a dedicated app, that was a predeccesor to threaded txt messaging, is such a deal-breaker for people. I had BB's for YEARS. I liked BBM when I had it, but never to point where I thought "I could never have another phone without BBM on it!" Honestly, when I got my first Droid I thought "this is just like BBM, only better because I can send anything to anybody - not just other BB users"
To me, threaded txt beats BBM hands down. BBM reeks of iPhone's walled garden - which is the philosophical antithesis of the entire android platform.
