I wanted one...
but to refocus on what it's [sic] user [sic] actually want rather than its own vision of the future of computing.
I would happily have bought an true Ubuntu phone or tablet if I could. That is, something I could do "apt-get install <foo>" on when on the move, and use with a Bluetooth keyboard and HDMI display when I got home.
However they never even reached the marketplace in significant numbers. The few that did were sold out immediately.
Mind you, it's not entirely clear if they were true Ubuntu or something completely different - like Windows Phone and Windows RT which were not Windows at all. If so, it was obviously a waste of time.
It's no accident that Microsoft's one success in the tablet space - Surface - is the one which runs real Windows.
