GPS information widgets

I've been busy with splitting out and rewriting the GPS information widgets from Mapper. I've also removed all the gdk rendering code and using cairo only.
Below is a screenshot from testing app:

The problem with maemo (and meego in a way too)

I've been a happy user of both the original Nokia 770 tablet, the N810 and N900. From the point of view of a normal user I've been very happy with all of them, they have done what they promised and as a user I don't have that much to complain about. But..

As a developer I was drawn to the original tables as it was gobject/gtk+/gnome based with no bloat of C++ or some java stuff.
Made it easy to create software and somewhat easy to support both desktop and tablets in the same software, with some ifdeffing for maemo specific parts (gtk/hildon). That was more or less working in 2007-2008, but currently it's a blody mess.
Trying to support Gregale, Diablo, Fremantle and normal desktop gnome in the same app is these days such a pain that I've almost lost interest to do anything at all (one reason for Mapper developing at a snail pace currently).
Even Fremantle, that should use the latest technologies, (and Diablo) is stuck in the stone ages, gtk is in the 2.10 series (3-4 yeras old) Gregale is even worse with 2.6. Same with glib. Then we have gnome-vfs and gio mess.
And tablets specific Hildon changes, 3 almost compatible versions. Then we have 3-4 different UI styles to support.

And now upstream gtk+ is moving to version 3.0 and GNOME applications should move over to it. GConf is going to be deprecated with GSetting/dconf.

Now what the fuck are you supposed to do as developer wanting to support all tablets and desktop in the same app?
