Barnes & Noble today made sure it wasn't excluded from the round of high profile e-book news from Amazon and Kobo by claiming some of its own successes.

It wouldn't give out device numbers but said it had sold "millions" of all Nooks and that demand for the Color was still beyond its expectations.
