I remember doing my initial forecast for the tablets this year, many thought my 8 million for 2010 was pretty aggressive. Now it looks like I was on the conservative end (as were most, as all those who predicted 4 million or so have now “revised” their forecasts). Now it’s looking like some analysts may be erring on the overly-bullish side, with one predicting nearly 50 million iPads shipped in 2011. That number would seem to assume a larger than anticipated cannibalization (maybe more than most anticipate) of the netbook and notebook spaces. It seems a bit aggressive to me, but with Apple, nothing is out of the realm of possibility.
