Yosemite seems to have its fans and detractors. Although the fans outweigh the detractors by a 3:1 ratio (based on observed info about Yosemite), will this lead to a market share loss for Apple? The ratio of detractors seems to be just about what it was when iOS transitioned from 6 to 7. I heard some claim that because of the change, when their contract for their phone ran out and it was time to get a new phone they would look at other phones instead of sticking to an iPhone. One such person was a neighbor that is now sporting a new Android based Samsung. When I asked him about an iPhone, he said "didn't even bother looking at them." Another telling sign is the reduction in sales of iPads since the release of iOS 7. Unlike iPhones, iPads aren't typically tied to a contract and a user can't be so easily locked into a platform. Now we get to Yosemite. Here we have just about the same percentage of hard core detractors at about 20%, which I think is extremely high for an OS update. In any case the options will include the following: 1. Switch platforms all together 2. Stay with previous version of OS X such as Mavericks, Snow Leopard, etc 3. Follow along with the Yosemite even though they don't like it. What do you think people will do? Personally I intend to select item 2 and as time progresses evaluate item 1.
