As a side note, if you plan to write apps for the DR and use IREX provided libs you should be familiar with glib/gtk+/cairo/pango/dbus stuff for common tasks and UI.
One problem though, is that libs versions are a bit older, so it's not possible to test everything compiling for a x86 linux computer.
Using other toolkits (qt, wx, etc) will be difficult because there are not ready for e-ink.
Anyway feel free to ask anything. And welcome,
Iņigo
