I think Apple has really helped evolve the smartphone concept, and for that matter they can be credited with a lot of the tech advancement we've seen over the last 20+ years. So to the degree that they have been the rising tide that floats all boats, props to them.
However, times have changed in the sense that the driving platforms are no longer hardware but software, and more than that we can see the benefits of open source software and the massive peer review that comes with publicly-posted code.
Sure, Android can improve. It should improve. But then again, look at iOS. It has also been changing and improving right along. And so, probably, has Windows Mobile, etc. This is market forces of competition at its finest and best.
There have been casualties along the way as well, such as Palm's PalmOS and webOS, and the smartphone project (I forget the name) which tried to have and use fully hackable and open source hardware. And looming on the horizon is Mozilla's own offering, Firefox OS, running on deliberately lower-end hardware.
This is how this industry should be.
