I've had the chance to play around a bit more with the MeeGo Handset UX on the N900 yesterday (1.1.80.0.20101001.1). Carsten provided experimental graphics drivers, which still crash at a few points, but for the first time provide acceptable performance in the UI. I also decided to build the gPodder MeeGo Touch Prototype UI against libmeegotouch. Unfortunately, there's no SDK yet, so I had to use zypper on the device (via SSH) to install libmeegotouch-devel, make and gcc-c++ and then take a long coffee break after entering qmake ; make. As it's using plain Qt, the TRG binary built from the Fremantle SDK worked fine on the device.
