The skins come down to a matter of preference Wiz...
Since I designed most of them, they tend to reflect how I have always DJ'ed (and still do when I test). So basically, more a reflection on me, then what Rockit can do.
I'm sorta surprised at the fact that not many have developed their own skins (other than Hank, and a few others). It's really very simple to do, and even before I put out the skinning reference last week, the skin mappers were heavily commented...
I guess in a way, I sort of consider that a complement -- look at VDJ, they have thousands of skins, built by thousands of users (bedroom DJs). Rockit is also used by thousands of users -- apparently, they are too busy making money outside the bedroom, to make skins...
Quite frankly though, I wish more people would write skins, external programs, etc. -- that's what Rockit is designed for. I just wrote a remote control app, that I'm in process of porting to the iPhone/iPod Touch. Anybody can do that -- I put the communications protocol specs in the manual.
Don't think of Rockit as a program -- it is an API (Application Programming Interface), that any user can modify easily
