oh I also have the Bigme Galy, which was a decent Android but unpolished device. Gallery 3 must be seen IRL to be appreciated, and it has a BW mode that's pretty fast and contrasty when colour is unnecessary (but you can toggle it to view covers).
8" slow refresh doesn't work at all (using Libby magazines as use case)...
(I also have a working KA1 for comparison to everything new I buy
)
