No kidding, Seeed Studio lets you create a (re)phone.

This just might be the coolest, most fun product we've covered in quite a while. The awesome people at Seeed Studio have put MediaTek's Aster SoC, the chip that we know from MediaTek Labs' Linkit One developer platform, to good use - creating a modular phone you get to build any way you want. Like Google's Project Ara, but less restrictive, more open to learning and imagination and just generally better.
