Forget Microsoft Surface and by all means ignore Apple's Mac. Because it is once-staid HP that is reinventing the PC today. And the hits just keep on coming.
Today's HP is the result of the corporate split of Hewlett-Packard last year, with the other uninteresting half of the company spinning off into something called Hewlett-Packard Enterprise, or HPE. It would be convenient if this story paralleled that event, if there was some way to explain that HP, the PC maker, "got its mojo back", or experienced some kind of resurgence because of the failings of its predecessor.
