3 x George running from PDA's, the lads are each given a loaded PDA in the morning, go off do their rounds and it is downloaded each night. Total time, less than 5 minutes.
If they pick up new work during the day, they write it on the PDA notepad and I copy it onto George at night.
I don't like the diary on George as it only shows you the houses for a selected round, I would rather it showed which rounds were due, so we have a spreadsheet of the rounds for sorting the rounds by date.
Any alternative would have to run off a PDA to be competitive with George.
