Looks like Ubuntu is ready for the tablet market. Now they just need somebody to put it on hardware. Plus somebody to make apps.

Looks like something I could put on the old Nexus 7 when Google stops supporting it
If you could attach a 10 inch Ubuntu tablet to a full size laptop keyboard and have it turn into a full desktop Linux computer I could see that. They have talked about docking the Linux smartphone to a keyboard, mouse, monitor and having the OS expand into full desktop linux, but I don't work at a desk much anymore.
But that idea of having your mobile device also be a full powered computer is tempting.
>docking the Linux smartphone to a keyboard,
I just docked the old ipad2 to a bt keyboard. Makes a great email appliance.
