According to Mediabistro, September 2010 ebook sales were reported to be around $40M. This year, September sales are reported to be $80.3M.

Now the optimist in me is thrilled to see +100.9% growth in the ebook market.

The pessimist is bummed that September represents a 10% drop from August 2011 ebook sales of $89M.

The realist is reserving judgment and waiting to compare numbers after December 2011 sales have been tallied.

The capitalist is concerned that overall tradebook sales have declined -6.45% since 2010.

The nihilist wonders what do books, sales, and half-full glasses even matter.

And The Dude says, "Hey, nice marmot!"
