This has been an interesting month when it comes to tablets. Apple has pretty much owned the segment, but Samsung reports it shipped 600,000 of its Galaxy Tablets in the first month, which may mean it’s a player. HP almost had a surprise winner in its Windows 7 Tablet, but it under-forecast demand. Acer ended the month announcing several tablets, including a phone that is just slightly smaller than the already-shipping Dell Streak. Finally, Notion Ink quietly signaled it was going to have its second-generation tablet available on December 9th. We aren’t even in 2011 yet, and the tablet wars are starting.
