CMV: Modular smartphones are pointless.

Unless you can swap out the processor and the RAM, they seem to offer no advantage over a regular phone. 

Magnetically attaching a speaker to the back of my phone is not better than connecting to a Bluetooth speaker. If I want a better camera Sony and Canon make wifi cameras that can interface directly with my existing phone or tablet. Those might be a little more expensive than a module but they're also way more versatile and can work with all my future phones and friends phones too as well as on their own. 

It seems to me that all smartphones are wirelessly modular already, they just weren't marketed that way. For that reason the 'modular phone' that makes the most sense is actually the Pebble Core as it's just the processor, radio, and memory, to which you can add whatever you want to wirelessly (maybe not yet, but soon I'm sure). 

Am I missing the advantage of physical attachment?

Hardware failure. Critical component of your smartphone fails? That's a time-consuming hassle even if it can be fixed - just hope it's still under warranty - and if it can't, have fun buying and setting up a whole new phone.

Module fails? Take it out and replace it when you like. Much cheaper, minimum hassle.
