Qt Components and the Plasma variety are API compatible. that's not 
accidental.

if the goal is to have something that is easily packaged on specific target 
devices (N9, e.g.) then that is indeed a packaging and delivery issue and one 
that needs attention. to just say "forget using KDE libraries" is the answer 
also means "forget using everything useful in KDE libraries, rewriting it 
ourselves and lose integration opportunities". 

to be overly blunt about it, the N9 and friends family of devices are dead 
ends; KDE's libraries are not. factor that into your decisions.

a) think about your users

b) the themability allows the same code to be run on different devices (that's 
the real intent of that functionalit)

c) the themability extends beyond "changing the colours and the pixmaps" and 
extends to device-appropriate functionality. have you seen, for instance, how 
scrollbars behave on the Desktop and Touch implementations?

d) themability is by far and away not the only reason to use the components. 
there are additional useful components included, integration with KDE library 
functionality (usually transparently behind the scenes) and an active and open 
development process that allows the components to grow alongside needs.

there is exactly such a replacement.

first up .. if you use a Plasma Package to contain your QML, you can create 
device-specific QML files and they are loaded as appropriate, transparently to 
your application. so you can have a device UI and a desktop UI.

secondly, Plasma QML Components have Touch and Desktop implementations and 
which version is used is done based on the device the application is running 
on. the API is idetical for each, but the interaction and other aspects adjust 
as neecessary.

so .. yes... it does this :)

if you have real world issues with Plasma QML Components, please bring them to 
the plasma-devel mailing list. we are very interested in making them a 
comprehensive and solid solution to the needs people working with QML have. 
that's even more so the case as we are increasingly relying on them ourselves.
