I think this discussion brings out a basic divergence in rider types. Do you view motorcycling as a sport, a lifestyle, or way of commuting/touring? I've always been much more concerned with chicken strips than I have with accessories. I tend to view straight roads as an evil thing needed to connect curves. The only thing I've ever mounted on my handlebars was a radar detector. Oh, and occasionally a GPS.
I think many here come from the Harley world and have always ridden cruiser type motorcycles. Prior to the R3T I never owned a cruiser. I liked the R3T as it provided a comfortable ride, something my age seemed to require. I chose it for the engine, and was willing to sacrifice handling for torque. And for quite a few years, it was quite satisfying. At the end of the day though, I got bored. The idea of 'it handles great for its size' while true, doesn't negate its size. While many capable riders can hustle a Rocket through the turns, it can't be considered flickable.
I say all I guess to explain my curiosity about things like cup holders and cigarette lighters. Not trying to be judgemental, just hard to relate I guess.
