Java ME was a joke.

J2ME isn't a joke, in the sense that it is an established platform with 
pretty wide adoption (especially among "feature phones" and older 
smartphones).

The problem is, to do almost anything useful, your app must be signed 
*by a Certificate Authority recgonized by the mobile device*, and as I 
understand it, there are only maybe two or three CAs that EVERYONE 
recognizes.

Whereas, while Android devices require your APK to be signed, you could 
self-sign it, or use any legitimate CA, and you'll be ok.

Whoever believes that Java isnt a platform for Android is just plain
nuts. The Java developers that I know and work with have all been
easily able to port their skillsets across to Android and have enjoyed
the new platform to play with.

App Inventor is a great way to get people started in developing apps,
especially kids. Could you build a 'real' app with it? Probably, but
it would most likely be easier to just write the Java. Maybe in the
years to come App Inventor will make more complex app building easily
possible, but not today.

Java ME is an important platform, especially for embedded hardware.
Android IMO will far surpass this in terms of importance. The next gen
of hardware that I am seeing some engineers building is going to be
Android based whereas in the past we would use all sorts of things. I
wouldnt be surprised to see far more hardware being Android based in
the years to come. The ARM based CPU's are quite powerful these days
as well as cost effective and well supported. Motorolla's iMX535 SOC
is a great example. You could build a laptop with that thing if you
were so inclined.

The primary areas where Java is being used may change, and probably
will, and IMO I expect Android to be an enormous part of that change.

My 2 cents

It has been estimated that 2.1 billion devices
support Java ME.

That makes it an important platform.

It does not prevent people from calling it
a joke on usenet, but the joke is really on them.
