Healthcare Input: mission impossible? Possible solutions

I was just about to write a post reviewing my Nokia 770 as an input device for study coordinators and investigators in clinical research, when I noticed a post in Colin Jervis' Future Health IT blog entitled Healthcare Input: mission impossible?. Colin sums up nicely some of the negative things I was about to write, including one or two that hadn't occurred to me. Ultimately, to my surprise, it made me more optimistic about devices like the Nokia 770 than I had been before I read his article.
