PCMag.com: "Barnes and Noble on Thursday introduced its eBook software on a new smartphone platform with Nook for Android. The software will run on phones with Android 1.6 or later. This is especially good news for users with Android phones like the Motorola Droid X or HTC EVO 4G, which both have 4.3-inch screens that could make for a decent-to-good reading experience."
Like Amazon, B/N is not so much interested in owning the hardware franchise as they are in selling content, this achieved by owning a significant eBook ecosystem (aka, platform) franchise, hence:
"... the company also announced its decision to move all of its Barnes and Nobile eBook software under the Nook brand name, with Nook for Android, Nook for iPad, Nook for iPhone, and more. Previously, it was called B/N eReader. With its Nook e-Reader and Nook software across most smartphone platforms, Barnes and Noble is trying to develop a strong platform to compete with the Kindle and Apple's iBooks. Barnes and Noble's Nook platform currently has more than a million titles and is available on iPhone, iPad, Android, BlackBerry, PCs, and Macs."
Elsewhere, PC World delivers an excellent comparison of Nook for Android vs. other Android-based eReaders.
