Slight tangent: why does Android use a VM, but not a standard JVM?

As said in this article: [C/C++ is better than Java when] very small footprint is required (these days that does not include most phones). You can get JVMs that run well in a few hundred KB.

The situations where a VM, but not a JVM are sensible seem to be totally squashed between C/C++ on one side and the JVM on the other.

There was some theory that it was to do with licencing (http://www.betaversion.org/~stefano/linotype/news/110/) but the argument got a bit obscure for me. Something along the lines of Google couldn't officially call it Java because it wouldn't meet the licencing requirements of the test suite.

But not being able to call it "JavaTM" seems like a small price compared with having an incompatible VM.
