Linux Tablet

[Geoffrey Wilfred Combes]

Is it true that an operating system by Canonical or another is available
for someone to produce a tablet comparable with others on the market?
If so how soon should be reasonably expect one to appear?
Presently I own neither a tablet nor a mobile phone. I'm not in a hurry
to buy such time-wasting toys but I guess I must soon. Should I buy a
tablet (say, rather than a notebook) for portable use I would prefer
that it has a Linux operating system.
By the way I am an engineer and a licensed radio amateur (time-wasting,
yes, but also a thinking hobby) so I am not averse to wireless
communication.
Your views would be of interest to me.
