Clossing Walled Gardens and Java vs. NativeApplications

With the risk of pointing out the obvious (and I'm not a programmer
folks, please correct if I'm wrong in any of the facts below).

The SonyEricsson P800 runs Symbian 7.0 that runs Personal JAVA (with the
JAVA Virtual Machine) as well as MID Profile 1.0 aka MIDP 1.0 (with the
K Virtual Machine). According to developers I've talked to, Symbian has
done a very good job when it comes to the implementation of Personal
JAVA on the P800.

Nokias proprietary implementation of the Symbian 6.0 core in their 7650
and 3650 only runs MIDP 1.0. No Personal JAVA or Personal Profile
(Personal Profile is supposed to replace Personal JAVA, no luck so far).

Personal JAVA is much more powerful giving the developer access to the
APIs of most features on the phone (phone book, calendar, camera and
filestructure). Personal JAVA applications can NOT be downloaded and
installed over a WAP connection however but must be downloaded to the
user's computer and transferred over Blue Tooth, data cable or infrared
to the phone.

MIDP 1.0 applications are run in a so called sandbox environment to
minimize the security risk. Therefore you won't be able to access any of
the functionality on the phone.

Do any of you know if this basic logic will change in MIDP 2.0? Which
are the key new features in MIDP 2.0?

Nokia, Symbian, Microsoft Smartphone and J2ME

It has finally happened. The news is already all over the place today: Nokia takes control of Symbian. It is obviously a smart move for Nokia -- it cannot let a committee comprised of its competitors to determine the fate of its most valuable phone platform (actually, I think the Series 40 is more valuable in terms of market share :).

But I perceive this as the golden opportunity for Microsoft Smartphones: the competition is now Microsoft vs. Nokia. Independent phone vendors might see Nokia as a bigger competitor (since it sells hardware as well as software) and give Microsoft a...
