Sorry but I don't buy into Tizen.

They already did a full native API revamp a few times, with no upgrade path every time it was done.

First they threw out the APIs they got from Meego and replaced with straight Bada C++, then they did a facelift, but kept the Bada feeling to the APIs[0], now C++ is out the door and one is supposed to use EFL with C.

Also the documentation leaves a lot to wish for.

[0] Similar to the Symbian C++ dialect, dual step initialization, handles, macros for exceptions
