They only make sense to me if all the functionality was based out of a single (or two) type of unit. Camera/Ram/CPU/gps/etc was all just a matter of software. Need more memory? Buy more phone-goo, designate it as RAM, and bam. Basically computronium. So, in conclusion, completely unrealistic in the near term, or our lifetime.
