The only problem with making this argument for Apple specifically is that their stock price seems to figure in revolutionizing an industry every few years.

They could stay a major player for a long time and do just fine, but they'd go from being "Apple under Jobs" to "Microsoft post-Gates." It's a long, slow sunset, and you sleep fine at night, but you don't win it all.

With that said: yup, the Apple Watch does put off the final sunset a few years.
