Well, mine is being used as a commuter bike at the moment more than anything. Also, as you said, if I had the extra funds available I'd do the same thing and have both.
As far as training goes; I've taken my motorcycle safety course and have several friends who have been riding street bikes for several years now so I am using them as a knowledge base (not using them as a guideline to ride like (i.e. their experience level)). Also I plan to take the advanced motorcycle course after several more months of commuter riding and weekend cruises just to have that extra bit of training under my belt.
I know the R6 is definitely not a starter bike, no one in their right mind suggested for me to jump to a 600cc bike as my first, but I guess I'm not in my right mind...
Though I've had 0 problems so far getting completely adjusted to this bike and feeling very, very comfortable riding it.
Another major reason I jumped straight to an R6 was because I've wanted, specifically, an R6 since their debut. I've always thought it was one of the most attractive street bikes available, and in my eyes nothing really compares. (Today's bikes are starting to look more similar, but still something about the Yamahas is incredibly attractive to me...)
