Another reminder is that GRead also runs on Diablo (Maemo4, N8x0) after a couple of lines have been removed from the UI files.

When you launch it as :

it's even half-way "hildonized" in that it looks less strange and the full-screen button works. It still opens separate windows, but they cover each other, and the tablets have an Escape button so it's quite usable.

The main issues are that the system menu is not converted automatically as in Fremantle, and the default font is too tiny to read, with the zoom keys not working.

These could probably be corrected more or less easily with a custom "maemo4" view, to make a workable GRead for the old tablets...

Speaking of which, I found another way to detect the host type and choose a view accordingly :

N900 : "Maemo 5" in os.environ.values()

N8x0 : "OS 2008" in os.environ.values()
