Thanks for the added info, I also wasn't familiar with Oyster. It also appears that Oyster offers the app for iOS and Android, but that still leaves a hole for e-paper readers. I'll likely be buying a Kindle Paperwhite in the near future, as the contrast, weight, and battery life just can't be beat. I do wish there was a competitive e-reader open to other subscriptions/retail stores such as Oyster. Why is there no open e-reader OS yet? Is the market demand for e-readers over tablets not there?
