The iPhone is bigger than their whole business. I don't see how this can be anything other than a huge failure for MS. The PC market is declining year over year and all the growth is in mobile, an area where MS is a bit player. And they were in the smartphone and tablet markets way before Apple! How is this not a disaster? RIM made money for a while too, but in the end they were doomed. I don't think that is true of MS, because they are just too big and do too many things. But people arguing that everything is OK because of the top line, I don't get.
