I bought myself an eReader for birthday/Christmas. I’d spent a lot of time researching the different brands and functionality, and finally settled on the Velocity Micro Cruz Reader. It came pre-loaded with the Borders app, but because its 3rd party, I can download the Kindle or B&N apps, too.
In addition to being an eReader, the Cruz has some tablet functionality. I’m able to browse the web and download games and other apps from the Android app store. Its tablet functionality is not perfect, but considering I paid eReader price ($120), I’m not complaining. And still reading books on it.
