Interesting article, though Android isn't needed, especially for something as limited in scope as an ereader. Most ereaders don't use Android. Sony switched to Android for T1, T2 & short-lived T3, with no advantage to them or the users. The T2 is no better to use than PRSx50 range and the T1 was worse.
It was fantasy, like a free iPhone – a mobile operator practice that should be illegal because it increases waste, limits diverse supply & puts up the cost of Mobile.
Cheap is Pearl. 🙁
