What is wrong with Android and why is Mer better?

From what I can see, in terms of support and applications availability, Android is far more useful.

Again, from what I can see, Mer is a work in progress albeit a very promising one.

But given the choice between the two - at this moment - why would one select Mer over Android?

Please don’t anyone tell me that this is off topic, compared to all that self indulgent haiku nonsense it is at least pertinent.
