I think the pflarm guys/gals had a good reason for setting a policy for updates. They probably thought of the case where the thing continues to work "barely good enough" and knew some lazy pilots would just leave it that way forever. That's no good either.
As we are starting to see with other devices the best solution would have been to have builit-in wifi and auto updates. Much like your computer... but then that adds cost and a whole other set of complaints.
