I've had my F900R for 2 weeks. I picked up during a service appointment for my former G310R. That little bike was a ball of fun, After a test ride on the F900R, I had to have it.
Mine is San Marino Blue with Dynamic Traction Control, Dynamic Engine Brake Control, and ABS Pro - though heated grips would have been nice. I've already created a list of accessories.
So far, after about 350ish miles, I have no complaints. It feels like a sportier, naked VFR800 (biased since I own one and love it).
