Well I can tell you that these are the things it has done for me while using an X50, RX65, V1, and STI.
1) More falses
2) Reduced sensitivity
What has it done to the industry as a whole? Well POP implementation has reduced sensitivity for a lot of manufacturers. So I ask you this do you think POP "protection" is worth the trouble? My answer is HELL NO since one has a better chance of getting struck by lightining than getting a ticket with POP.
