Why Doesn't Android Natively Support Bluetooth Keyboards?

I kind of understand why the iPhone does not support the use of Bluetooth keyboards: Steve Jobs hates buttons/keys of all kinds! Just look at the silly one-button mouse that morphed into a no-button mouse (which actually has “hidden” left/right buttons). Then, there’s the iPad which finally gives Steve a big(-ish) screen computer with no keys and very few buttons. [Note, I really want an iPad :-)]
