We just started on DIAD 4 yesterday. What a headache! I guess it is good for those of you on PAS/EDD but I would rather be back on DIAD 3. The shift button is a joke when you have to continually go back and forth to key in the address and street. God forbid that you have a 1Z that won't scan. (of course you know that they are giving us extra time for that) No wait..... they took time away from us because the DIAD is so efficient! Only thing I like better is the scanner seems much improved and I never wear a watch so it is nice to have the clock present on all screens now. I would go back to paper in a heartbeat if we could sheet 6 numbers and an ID again. Where have the good ole days gone?
