Congratulation’s I think you’re coming on board at an exciting time. Firmware 3.xx is out for the AF II and I equate that as 11.xx was to the Ultra/standard. I came from a standard also, still have it but have not touched it.
And also last week Fractal came out with a new USB driver which is working flawlessly or at least my two systems.
New unit, different animal, very small learning curve. Being a standard owner you will have no problem right out of the box. And if you are like me, I always programed my standard with Axe Edit, just for speed alone, but you will find new buttons are much nicer, and the speed knobs on the front are awesome (ABCD) and these knobs are probably your only curve which will pass very quickly. I still prefer the editor but navigation on the unit itself is Way way better.
