Motorola did come out with a 'Webtop' in 2011 before they got acquired by Google [1].
The laptop dock gave you an Ubuntu desktop to do work in. They even ended up opening up the code (but it was pre-ICS so good luck making that up to date).[2]
'ubuntu desktop' meaning a very crippled system that only allowed access to Firefox. Which was rarely updated and even then not for long. There were some efforts to patch it up to make a more full system but I don't believe anyone was ever successful.
