Was told by the F/A on my LGA-PIT flight last week that as of 10/26 customers will be allowed to use their cell phones upon taxiing to the gate after landing. Of course I find this to be just another irritant to the flying experience of late. Come on, are you really that important that you can't wait until you get off the plane to use your nauseating cell phone? I know I don't want to hear mine ring and don't wish to listen to another fool talk loudly about his/her business dealings. Guess those types of people don't know about decorum and manners.
