"First, let’s look at the numbers. Apple has sold about 28.7 million iPads since the device hit the market in March 2010. That’s an impressive figure, to be sure, and Apple is clearly dominant in the tablet PC market. But compare that to the 400 million licenses of Windows 7 that Microsoft has sold since its July 2009 release. Moreover, those iPads don’t seem to be replacements for desktop or laptop devices. Owners of iPads are “not likely to report they’re making tradeoffs on purchases,” says Sarah Rotman Epps, consumer analyst with Forrester Research, who also notes that owners tend to be “relatively wealthy individuals.”" - LANjackal
