Well, if it actually solves our problems, why not? But two things: as far as this thread is concerned we were not talking about android on ereaders in general, but about android for onyx devices. It may be the case that for some companies like nook or sony the effort of adapting android to an ereader's needs pays out. But it's too much work for us users to port Android to a device that has no official support for it.
the other thing is, that the article on the-digital-reader.com also wonders, whether there actually is an android app, that has the functionality that we are looking for. And I'm wondering, too: Is there an Android app that does what we want _and_ that's likely to run on eink device?
