Once I saw that Kobo was going all in on the color e-readers I decided I'm going to sit this whole trend out and bought another Aura One. Between it and the one I currently own they should carry me for a long, long time.

The Aura One is essentially perfect. The only gripes I have are the USB port and non-removable battery. It is a bit slow with the stock OS but with KOreader it runs amazingly well.
