Having just received mine, and being used to my Fuji camera, the buttons were absolutely no problem. In fact, I thought the menu was more logical than most. Sure, it could be better but personally I wouldn't list it as a "con".

And, as the original ipod itself showed, mechanical wheels can be prone to mechanical problems, so depending on care the buttons may have more longevity... sensible for an "entry level" digital SLR.

All depends on how you look at it.

The real shocker was the grip, I'm a tall guy with big hands and long fingers. I expected the grip would be an issue. However, holding the grip with my fingers folded against it I actually get a more comfortable and stable hold than the much larger Fuji grip. While I still want to get the battery case, this was a pleasing surprise, and definitely proves YMMV.
