Many of the Android applications can be installed, in particular Pleco ('Beta 7' and 'Beta 8').
As a reader software I use Cool Reader 3. To look unknown Chinese words, I copy them to the clipboard, open Pleco and look at the entry in one of it's dictionaries.
The only problem that I have with Pleco is to use cutom Chinese fonts. Even if I install them in the given location, the default Android font is still displayed.
I know that Pleco (as a lot of Ancroid applications as well) is not optimized for E-ink devices, but I can live with that.
In general: Pleco for Android Beta 8 is close to release. Gread job!
