I disagree. And Sun disagrees. And the fact is, Dalvik doesn't even run Java bytecode, nor follows the JVM spec.

Also, Dalvik is an interpeter and thus can forget about any kind of performance comaprable to C. Unlike JITs, which can on certain workloads. Of course, that does not mean Dalvik/Java is useless for interactive (read: 99% of wall clock time waiting for user input) stuff.
