> non-tech management MBAs running Google are all using iPhones

That's a kiss of death. I remember while working at Windows Phone team at Microsoft, a lot of program managers and designers were using iPhones and Macs. Unsurprisingly their own product never got off the ground because they failed to develop a vision for it. Android at Google is in a slightly better position, but this kind of attitude of not using your own product but preferring a competitor's one leads to inevitable decline.
