So far this year has had a lot of (justified) noise bounced about advocating responsive design, not so long ago Henrik Eneroth did an excellent post and suggested re-design of the browser as we know it. Pulling out responsive design from within the browser viewport to the application level.
The results make a lot of sense, elevating the buzz wordy "responsive" design from just something for web designers, but as a way of thinking to design in general.
Here's his original post (via @cameronmoll):
Mozilla have released screenshots of the user interface for Firefox for Honeycomb Android tabets which is very close to what's described in the original post, not quite a full blown re-think of the browser for the desktop, but a move in the right direction, and a signal that Mozilla are very much switched on.
