One analyst is saying he expects that Apple will sell 7 million copies in the first year. Considering Apple selling 1/2 million the first week, and possibly more the week of the 3G release, there is a good chance it is realistic.
Another poll showed that only five percent of those polled said that they were definitely interested n buying an iPad. A big win for the naysayers, right? There are 300 million + Americans. If 5% of the population buys, that is 15 million iPads and a whole lot more people in the rest of the world besides. No matter how you shake it, the iPad has a good deal of interest. And it is buying interest.
