Why not? What prevents Oracle from compiling a JVM for RIM Playbook OS
and offer it for download from Java.com?. Vendors can just pacakge
app-installers that check if the JVM is present on the device and if
not, download it Over the Air and install it.

H*ck, Sun even offered a MIDLET 1.0 Java VM for PalmOS a decade ago.

Java adopts the native OS look an feel (Java SE at least) I´ve seen it
on Windows and Linux. There´s no technical reason why that can´t be
made in other OSs too.

Just because there´s no central store to retrieve apps. Sun had it
right in creating a Java App Store. Oracle should refloat that effort.

Abonut J2ME apps, cross-platform works, I run Google´s GMail Java ME
app on my Palm Centro, even while it isn´t a supported configuration.
It just works.

What I envision is being able to click on a ".jad" http:// link on a
tablet browser, and (after the Java VM is configured as helper app)
the OS offering me to run the mobile app as a desktop widget on the
given tablet.
