Are you using it via X or via Framebuffer? How's the performance?
I use it over X on Debian, SHR and OM2009 and feel comfortable with performance, apps run more or less as with other toolkits. Asap I'll write some snippets to test the new QGraphicsView performance, but I doubt a float only based canvas engine may perform well on the freerunner. In every case the major CPU effort may seems a little thing in respect of the slow device video bandwidth, I'll report back when free time will be available. The following blog may be interesting [1] And take a look at this nice video too , there is a neo in action, hoping it's not a fake :) [2] >> I'd like to see this framework supported in the shr/import branch, and >> may be added to the feeds. > > I agree.

I want to add that three major factors should contribute for a better QT in the next future: QT on Symbian, Maemo will drop gtk and adopt QT, the trolls experience on embedded devices.
