Sony PRS-T1 6" Digital E-Ink Pearl eReader with Wi-Fi (White)
The reader can be easily rooted and then full Android is available to you. I have two of these readers and I love them. A hint: once rooted, get rid of the apps \\"telephony provider.apk\\" and \\"phone.apk\\" because they just drain the battery and are not needed otherwise (as this isn't a phone). This is an incredible device (especially once rooted) and I cannot recommend it enough.
