That is exactly why you can't fall behind... ever. In the tech game, catching up can be and usually is impossible. Even for a juggernaut like Microsoft that has all the resources in the world, INCLUDING a base of over 90 percent global PC users.. they still couldn't do it. In fact, the reason MS is so keen on pushing everyone to Windows 10 is not because they want to better than mobile share, but because they were also starting to lose share in the desktop operating system market. Windows 8/8.1 probably lost about 1% or more market share to Mac. This and the popularity of iPhones creating windows to mac converts, MS realized that their ENTIRE product like is on the chopping block if they don't get their acts together. At this point they are still not out of the woods, they need to write off the whole Windows mobile fiasco and just concentrates and keeping their market share and not losing any more to Mac. Just a few more percent loss could suddenly avalanche to record drops in their PC market share with Apple gaining. In business, nothing is guaranteed, and if you snooze, you lose.
