first reviewed the combination touchscreen/E Ink "dualbook," we wondered whether its neither-fish-nor-fowl design would catch on -- especially priced at $500. That price dropped substantially with its successor, the Pocket Edge, but neither device truly found its feet, in part because of a lack of applications and no updates beyond Android 1.6. And now comes word that the Edge store has officially closed, with customers having until May 27 to download any purchased content. It all points to RIP for the Edge family, and Good E-Reader claims to have recent confirmation from the company. In its goodbye message Entourage steers users toward the Amazon app store, where it notes "you will now have access to a lot of Android Apps that Google would never give us access to." Obvious bitterness aside, the team reportedly has a new device in the works, this time in the typical slate model.
