there's also the fact that phones have relatively limited memory. I suspect the Dalvik VM runtime memory footprint is much lower than that of the JVM.

I know that was a design goal, e.g. the bytecodes after translation from JVM to Dalvik are smaller. I also seem to remember hearing that not all of a JVM's library is supplied with Dalvik.

Also, hasn't Java ME stagnated? I.e. it's stuck in at Java 1.3 (which Oracle has promised to address).
