The iPhone "nano" makes no sense to me

I keep hearing rumors that Apple is getting ready to launch an iPhone "nano" in China. Problem is, an iPhone "nano" makes little sense.

I'm not going to dwell too long on the idea of a "nano" iPhone because all these rumors and speculation seem to lead back to analysts or pundits who think that a "nano" form-factor iPhone makes sense. But it doesn't. Here's why ...

For starters, what advantage would a "nano" iPhone offer. After all, the reason that the iPhone works is that the device has a touchscreen that's big enough both to use easily and which makes the device multi-purpose. I just can't see how a small "nano" screen would work.

But let's forget about the screen for a moment and look at two other problem areas:

• Battery - Cramming a batter that would power a "nano" iPhone would be a real challenge.
• Apps - As far as I'm aware, iPhone apps screens don't scale to smaller screens.

The iPhone "nano" sounds to me more like wishful thinking than anything else.
