Nadav Savio, now a user experience designer at Google (GOOG), and mobile usage expert Jared Braiterman, founder of Jared Research, wrote in a 2007 paper.
From the Business Week article “Moving to the Mobile Web”.
They do mention a few design/UX agencies in the Business Week article including Punchcut (who I only heard about last week as a good friend of mine just left Frog design to join them, also follow them on twitter), and of course the good people at Adaptive Path who have always focused on the people and not the technology.
I know most of us with significant web experience have been hearing for years how the mobile web was going to take off, but it really does feel like the current environment has got some very disruptive forces and new entrants that are going to heat up the competitive environment.
Highly recomend reading GigaOm’s post this morning titled Symbian, iPhone and the new mobile reality
