Apple Inc.

Is the comparison valid?

According to Andreessen Horowitz mobile analyst Benedict Evans, this is a good instance of the scale of mobile. Though Apple Inc. (NASDAQ:AAPL) makes only the high-end devices it succeeded in selling more units than the whole PC industry.

Some analysts can neglect these comparison altogether by asking how one can compare the iPhone and iPad with the number of Windows PCs sold worldwide when these are somewhat arbitrary device categories.

Others can, however, argue that the consumers today on a large basis are porting their PC works on other devices, and all of them are mobile. This trend will most likely increase in the future.

Earlier, in January, a report from Horace Dediu of Asymco said that the total number of Apple Inc. (NASDAQ:AAPL) devices sold would equal to the number of Windows PC at some point of time this year. In the analysis, Dediu wrote that there were only 1.18 more Windows PCs than Apple devices. However, the comparison is not very apt as the analyst has included iPhones, but excluded Windows Phone and tablets. However, the number of Windows mobile devices to date has been very low, which would not affect the comparison very much.
