I find this interesting in contrast to Nexus devices. Two or three years ago, most Android phones had SD cards and removable batteries. These features have been conspicuously absent from recent Nexus phones in spite of their appeal to the power-user and developer markets who are among the most likely to want such features.

I hope it gets some traction. I'm seeing a lot of sameness in high-spec Android phones, and something like this might help manufacturers learn what kinds of variations might sell without having to take the risk of mass-producing and marketing a new model.

P.S. - if any manufacturers are reading this, I want a high-spec Android phone the size of an iPhone. My Nexus 5 is somewhat uncomfortable in my pocket and too hard to use one-handed due to its size.
