Also Nokia Communicator 9210/9290 supports personal Java. It was
a choice by Nokia maybe also due to interface (One-Hand operated no
pen no keyboard) issues and hardware features.
Also the P800 is considered a Communicator so a different class from
3650 and 7650 that are Smartphones.

The basic idea of MIDP 1.0 sandbox will remain as avoids unauthorized
accesses to the phone resources. But rel. 2.0 is giant step forward...
Here are the main improvements:

For my point of view PUSH support is a very interesting feature
introduced by MIDP 2.0

I do not think this will change soon as Java must have standardized
APIs that do not permit you to access the low-level hardware
features that are different from phone to phone. Anyway I see
Java and C++ as two different options you should have both.
And also very important is the possibility of distributing an
application
by other means than OTA. Is not just a matter of developing "fun"
applications without the operator control is also a matter of being
able to distribute with low costs and in a shorter time like with any
other kind of software.
The Internet has borne thanks to freedom of distribution and
connection on open standards and we do not call it just a
"fun" network. ;-)
