While there are a number of players in the tablet marketplace, Apple clearly dominates the market, further evidenced by analyst shipment estimates. As seen in the graph above, the iPad’s usage share advantage over its closest competitors is now nearly 80%. Most other players in the market exhibited month-over-month declines, with one notable exception being Barnes & Noble’s Nook.
When the only other tablet showing any growth at all is the Nook, that’s pretty good. (Those Surface numbers — ouch.)
