Comment 1.6 is done... (Score 1) 222
As a soon to be full-time mobile game developer, I had done some research into the Android platform and it turns out targeting version 2.1 and up is the way to go:

12.6% are still running 1.6 and 1.7. Not only that 2.1 devices are much more capable with faster CPU and GPUs.
In my case, I plan to make an engine that run OpenGL ES 2.0 only. Screw 1.1 and it's fixed function pipeline and its wimpy ARM 9 CPU's!
