Cool! I've been thinking of getting an Android eink tablet to try Readlang on.
I'd love to hear how it goes! If you don't mind, after giving it a whirl, let me which model you have and how well it works :-)
The word is getting out about Readlang. There's no paid advertising and I'm a n00b at marketing but slowly learning. It seems to be growing, but please lend a hand by telling your friends :-)
