And even if you can, why would you? I currently have a Moto X. If something bad happens with it (stolen, damaged), I will get a 180 Euro Moto G. It's still not pocket change, but far less to worry about than a 699 Euro iPhone 6. I want to use a phone carelessly and not put it on a silk pillow or use it with a case or screen protector.

Some of my friends have Gs, and they are very happy with it. I played with one, and I really liked it (especially the first gen, which has a nice size).
