"Unfortunately for Apple, the number if respondents saying they had heard about the tablet but were not interested in buying one, doubled from 25% before the announcement to over 50% following the announcement."

Of course, that 50 percent who are interested is plenty to make the product a success, provided many of them actually become buyers. (Learn more about the study in by Greg Keizer).

I think we may be being a bit hard on the iPad. I still don't think it will become a big enterprise computing tool, even if it does "run" Windows 7 (). I also don't think traditional mobile line-of-business applications--think your UPS driver--will start carrying iPads.

But, entertainment, gaming, and e-reading, especially in education, could still make the iPad quite a winner.

Apple already has the ecosystem in place--developers, content, shopping--to make the platform immediately useful when it arrives.
