I strolled into the Mall of America Barnes & Noble and stopped at the Nook e-reader desk.
A store clerk materialized and I drilled him with questions – is this 3G or wifi? How much memory does it have? How much space? Is it backlit? How does this compare with an iPad? Kindle?
The clerk explained that the Nook was for consuming content – magazines, books, etc. – and that the iPad was more useful for producing content.
