After using my A81 for about a month, I've decided it's not exactly what I was looking for (even after getting Android to run on it (kind of)). My reading habits (lots of rapid on/off sessions) are apparently more suited to an e-ink device - I found the battery discharge of the A81 too rapid, in this scenario, for my tastes.
Anyone interested in this still-interesting, still-nearly-new hardware, please look

Thanks!
