TechCrunch is reporting insider information that the big and much-anticipated Microsoft announcement tomorrow is an e-reader and streaming media tablet produced in conjunction with Barnes & Noble.

One loser

Let’s be honest: Windows on a tablet is, at the moment, a loser. Currently, Windows is a tiny, insignificant slice of the tablet market. There’s hope in Redmond, and maybe even belief, that this will change soon, but no-one else is holding their breath.

In this chart from IDC three days ago, Windows is “other.” Get out your microscope.
