@JulmaHerra,
You may have hit the nail on the head. A small device as a thin client in a platform-independent way is a factor I missed. I agree it may have some really valid uses and can ever future-proof your purchase. You do not need to upgrade every few years, the server does (and your subscription covers it). If done cleverly, your device can 'run' Windows, OSX, Linux or Future OS 9000 simultaneously, without having to reboot.

Still, it is not something I would call revolutionary, groundbreaking or shaking foundations. The terminals of the 1970s did exactly the same thing, as does anyone using one of many remote desktop solutions today.
