Is there a device that uses wifi/bluetooth, touchscreen graphical interface (similar to a smartphone), can download and support droid apps, and, in particular, supports the Overdrive app, which is the official app used by nearly all public libraries for browsing, checking out and playing audio books? My old smartphone works great but it keeps prompting me to activate it, requiring a multi-step process to stop the activation process so to get to the home screen. I do not want an MP3 player that does not support Overdrive. Kindle would work but they are way to big to use as an audio playback device. Thanks.
