Apple is still dominant, to be sure, but I wouldn't count on it's numbers looking so good next year. In 2011, my house only had an Apple tablet. In 2012, we've had two Android tablets, and one iPad. Next year? I can't say for sure.
"Apple continued to win out in terms of tablet market share this past quarter, according to the latest figures from ABI Research, with a 55 percent share of all shipments during the period. Thats a lead it has had since 2010 when the iPad was introduced, but its also the slimmest lead its ever had, and represents a dip of 14 percent versus the previous quarter. At this rate, Android could overtake the iPad for tablet share sometime next year, something which seemed unlikely or even impossible in 2010 and 2011."

"Sales of Googles (GOOG) low-cost Nexus 7 tablet have reportedly topped Apples (AAPL) iPad over the holiday season in Japan. Nikkei cites market research firm BCN in reporting that a survey of 2,400 stores across Japan suggests that Googles 7-inch tablet accounted for 44.4% of all tablet sales by large electronics vendors in the region. Despite the launch of the iPad mini, sales of Apple tablets were said to account for 40.1% of all tablet sales over the period. It is unclear if Apple stores were included in the firms poll."

There are plenty of glowingly positive prognostications for Apple as well, but I think these two articles are the canaries in the coalmine. My guess? Apple will do what it did to computers and move us on to the next thing, leaving the Android and Windows folks to fight over scraps in a dying market. I am wondering what is next, because right now, my iPad completes me
