No, I'm a beginner and fly on a buddy lead basis most of the time. Instructor has an ancient FF6 or 7 ( I think) and I have 6YG. It's got exponential for aileron and elevator and one or two other gizmos. I have absolutely no intention of fiddling with the other stuff and if I get a second plane I'll trim it out if I need to (actually I'd get one of the instructors to do it probably if I couldn't do it myself). I'd love a computer radio (because I enjoy all that sort of thing) but I'm so enjoying flying the plane (figure of 8s, approach and land, that sort of thing) that I don't see me outgrrowing my basic radio for ages.

Newcomers to the club are bringing their 6EXAs but realistically they are doing the same sort of thing as I am. One old-timer recently bought a computer radio so that he could settle down a Chantilly Lace which was much too difficult for him to fly on a basic radio. That to me is the purpose of the computer kit, not figure 8s on a trainer...
