It may not be obvious to everyone, but the current shape of Symbian components on Qt Components gitorious repository is pretty good. Just for kicks, I compiled it in N900 scratchbox and took a screenshot:
No special steps were needed to build the repository, just
git clone git://gitorious.org/qt-components/qt-components.git
./configure -config symbian3
And then run examples/symbian/qmlgallery. Earlier, we packaged "meego" style components for N900, but as the public version still relies on MeeGo Touch libraries, the Symbian set of components could turn out to be a lighter solution. If there is interest, we will package a snapshot of this version as well.
