I have been running a beta version of the 1.07 firmware for about 2 weeks now and believe me it has been rock solid. The updating process could use a little polishing, but hey they are making an aquarium controller not a software package. As long as I can figure it out in a reasonable amount of time, I am fine with it. I can't, for the life of me, understand why people are hung up on the graphing, but it is a feature that people want and it should work. The display is far too small to be useful for looking at graphs. I'll wait until an RKE version of myReef comes out to worry about graphing. I have 100% of my system running on the RKE now and I am very confident in the system. If you haven't upgraded firmware to 1.07, you should. DA will be at RAP if you have questions for them. They will probably be showing off new hardware as well.
