Yeah I haven't got mine yet. Still on the "training wheels", although I intend to get my endorsement one day. I'd be interested if people view this list as correct:
Advantages:
- Feel like a "real pilot" (tm)
- 2-5 kts faster aircraft
- No nosewheel to collapse on dodgy strips
- Land on shorter strips (?)
Disadvantages
- Poor visibility in taxi
- More difficult to handle on the ground & takeoff
- Ground looping can f--- your aircraft [my biggest worry]
