If you must know, it was a Nook Color. It sucked so bad, but I was only asked to get it to test an app we were developing for. Slow, and a pain in the neck to get the SDK to recognize - registering the device as a development device, not showing up on Windows, but showing up on Mac, trying different things on the command line. The Kindle nor my MyTouch 4G was never this hard to deal with. Glad to have returned it within the return/exchange period.
