About Android:

Old school software-guys can never understand and agree Java (or any interpreted based language) software platform can be efficient both in performance and battery wise. Although Android has already proven the points by selling numbers both to IT-experts and to common people and anyone can buy a Android device and see himself.

My friend's dual-core 1.4 GHz Samsung Galaxy S2 can run longer
and more complex (Java) applications with 1650 mAh battery, than my N900 (with 900 Mhz CPU and 2x1320 mAh battery) which have mostly native (c++) applications.
Many old school software professionals just won't believe it would be possible, but it is, and anyone can try himself quite easily.

I am referring to this discussion thread:

The best platform for me would be the main branch Linux kernel based OS (OSS Tizen) with Dalvik VM so Android-applications could be run as well as in any high-end Android-device.
I would not miss Qt, although I wouldn't mind having it also as an option. I hope Samsung will make it happen. Tizen alone without Dalvik support may not succeed.

And about Nokia and its stock price; both deserve the state they are in.
