Yes, in your interpretation, not what reality is.A curious interpretation, what that graphic shows is the same that shows the growth of a technology when its price decreases. It has nothing to do with having a GUI or not.
Mac prices are not decreasing, they stay flat for years and then go up. The entry price for the cheapest 27" iMac in October 2009 was $1,699. The entry price for the cheapest 27" iMac since October 2012 is $1,799. Meanwhile Macs outgrew PCs for how many consecutive quarters? Technology adoption is not a matter of price but of usefulness.
Most people started using computers in their homes because GUIs made it a lot easier. But still to hard for my mother, she couldn't figure out what to do in a multi-window multi-tasking environment. Her personal computing started with the iPhone. One App at a time, no context information to mess up with.
Yeah right. So much that Microsoft now is doing its own high-res display support in the same way Apple did with the Retina MBPs.No, a sharper, more clearly defined image is pretty much a given with a resolution bump.
Windows 8.1 will finally add high-res display support
„The Surface Pro, Lenovo ThinkPad Helix, Toshiba Kirabook, Dell XPS 12, and many other high-end Windows 8 machines suffer from the same nasty flaw: even as their high-resolution touchscreens are crisp and beautiful, the user interface is often too small.“
Told you so.
„Windows 8.1 will add support for high-density displays, finally scaling the user interface to these increasingly high-quality devices. And to get there, Microsoft appears to have adopted the same strategy that Apple used with its Retina display-equipped iPad, iPhone and MacBook Pro.“
Improvement but not innovation since someone else did the doubling-trick before. The 15" MacBook Pro Retina introduced in June 2012 is already in the middle of its second generation and proper high-res display support is still only announced for the coming version of Windows. That right there is your example of unique innovation only available in a Mac.
