I love variety in technology. I like choices. But there is a cost for such. For one thing, there's more to possibly go wrong. Today some Android phone users updated their devices to KitKat version 4.2.2, after which their Exchange email stopped working. After a couple of hours of web searching and reading hundreds of forum posts, I found this article, which clearly defines the problem, and more importantly, the response which clearly states the solution. Thank you smart person. Now I can go to lunch!
