Android will put all the nails in the coffin of Microsoft. Around the world people do not have the disposable income we have in the USA. The poor will get computers and the 3rd world counties will for many. In the developing lands we want something that works like an iPad and if we don't have the ability to buy one for each family member we will use android. All the developers that don't have their head in the sand or their ass have seen this and are writing android apps for the billion devices out there already.
There are a smaller group that have more disposable income and have purchased several Mac computers, iPads and iPhones. Not the norm but a big number.
The dying breed are the ones stuck to the Windows PC for gaming, for enterprise apps and old fashioned MS Office. Any PC user with a brain would have ditched MS Office some time ago for the open source office packages and been quite happy. Windows 10 for $x per month, that will create a thermo nuclear war. Just because you build a huge cloud with your spare cash your sitting on does not mean you will attract customers. You leave a $250 steak at your kids lemonade stand it will not sell no matter how many you buy, how many you cook or how many you have on display. Give that steak enough time and you got yourself some smelly food that is attracting flies and other undesirable animals. Your moving product but not in a sustainable way.
Good luck MS, I am ready for a change. I am sure there were longtime IBMers that we ready for IBM/Mainframers to shoot themselves in the foot when MS was the underdog.
