I like to think of it from a bit of a environmentally friendly perspective (but there are massive benefits to convenience as well). How often do you need/want to upgrade your PC/Phone/Tablet? Those probably have a fairly regular cycle. What about your TV? Monitor? Keyboard? Other I/O devices (ignoring that we've had a resurgence in monitor technology in the last few years). These things don't have as consistent an upgrade path. If rather than upgrading your PC AND phone AND tablet on a 18 month - 3 year cycle, you just upgraded one small device every 24 months. You still use the same monitor and keyboard, your tablet screen (which I suspect the tablet will become little less than a touch screen with built in camera and I/O to run the OS) and other devices. You're saving quite a bit in resources. One 'local' drive that you carry with you, and a bunch of cloud storage, all your apps across all your devices, no logging into a service on device X only to find that when you go to device Y you have to login again, but you've forgotten your password so you reset your password which means that you're not logged out on device X. Etc. etc.etc. there is value.
