Not sure if entering the full Lat/Longs is the solution as this now gives you more digits to potentially screw up, such as Capt Groper posting his waypoint of N5030.0/E03000.0 which is E5030 (Apologies if you intended to post a East waypoint)
The lesson I take away from this is to slow down, be careful and double check.
Jeppesen and the associated avionics manufactures should have also gone to greater lengths to better disseminate this information ahead of its implementation.
