What Matthew said.

It's like trying to teach someone who never took the training wheels off 
their bike how to ride a bike that can't ever have training wheels or go 

I hope to God I'm never connected to a Medical device that used QML. A 
better question would be "How did you even get that through the FDA 
approval process?"

A stable API is what is required for long term production. It will be 
interesting to see what your opinion is 10 years from now when the QML 
code you wrote last week will no longer run on the "current" QML VM.

Just how many times has someone re-arranged the header files in Qt just 
to make it more aesthetically pleasing? A lot. That minor little "tweak" 
busts builds wholesale.

As far as the "not a 3 OS world anymore" you are correct. It's a Yocto 
Linux build or a Windows build. That's the embedded medical device and 
industrial controller world. Under the "Windows" heading is WinCE, 
Windows Mobile, whatever that Windows 7 embedded thing is/was that many 
companies bought the source to, and the original flavor of Windows, DOS.

Hopefully, very soon now, the KDE community will announce what the 
post-Qt development tool set will be and the embedded world can not only 
move on, but get some stability back. From everything I've heard, we are 
all waiting for KDE to make the decision. Hopefully they will mandate 
the require API stability and header files not becoming Easter Egg hunts.
