Today was a milestone. We demonstrated the Linux version of FieldWorks TE to a group of people at the office chapel time. It worked well enough for the demo, in that it wasn’t slow and didn’t crash, and the people were impressed 
Progress has been very rapid in the past month or two, for several reasons, but today was the first time that we felt TE was ready to show to others. It was helpful to have the extra incentive of a scheduled demo for the final push to get things working on a non-developer machine.
