Been using Campy EPS since V1: V1 minor problems, V2 a few less problems, V3 none! As for the MyCampy App, only issues on the very first release. I have come to the conclusion that most issues related to Campy EPS is related to who install it. I personally have learned to master the groupset myself and I know every time it acts up it has been because something I failed to do right the first time. I do use a RECORD front derailleur or a modified SR Front Derailleur with a Record cage. To my taste, it shifts crispier and it is more durable.
As for Shimano Ergonomics and such. I am do not like the quality of the Shimano goods. The rubber on the hoods is thinner than Campy and some of the metal parts tend to discolor with time. Campy, however, needs to get on the program with their interface and connector choices.
I have a Pinarello F8 and a Pinarello 65.1, not going to the F10, because the differences on the F10 do not justify the expenses if one has an F8, especially if one uses Campy. Hopefully next year Campy will offer a better Interface Unit that one can hide inside the frame. Also, Fausto Pinarello mentioned something about wanting to become "the Apple Computer" of the bike industry. So get ready to see a frame refresh every 12-18 months!
Enjoy your new rig! Like a friend says: "you don't put soy sauce on your Italian pasta!"
