A successor to Barnes & Noble’s popular Nook Color e-reader may be in the pipeline. Rumor has it that we might be seeing it really, really soon – as in, this month soon. Digitimes reports that the updated Nook will be more of a tablet than its predecessor and will better incorporate email, music, games and other critical apps. Remember though, the Nook Color is first and foremost an e-reader and it's designed with that in mind. Greater performance usually comes at the expense of battery life and the latter is much more important for reading. With Amazon rumored to be preparing a November-release tablet -- one that we can all presume is designed to be a Nook Color killer -- the timing seems right. At any rate, anyone thinking of buying a tablet might do well to wait a month or two to make the most out of the tablet war. Source: Digitimes
