falling from relevance isn't necessarily a guaranteed outcome. inability to change is a guaranteed death march.

MS can always choose to innovate, build new products, bring new R&D technologies to the market, etc to combat Android. It will try and try again till it gets it right. If there's one thing MS has, it's tenacity (and a lot of money) to keep trying.

I believe MS will eventually get it right with Windows Phone because Google is now moving Android into 2 different areas for improvement
a. Introducing new features
b. Providing more frequent updates by moving core OS services and features into packages that can be updated more frequently and easily.

Both of these are territories that MS is very good in fighting.

The rise of Android is partly due to the fact that it is cheap (almost free depending on which licensing model you pick) and it's *almost* open source (in the early days anyway).

I'm not counting MS out of this race yet even if they are the underdog now up against crazy odds.
