Hi Michael,
I used a C5 (not a C6) for quite a while and the main advantages of having a unit like that are its speed and improved low-light accuracy over the i1Pro. Once a colorimeter like the C6 is profiled against the i1Pro, it becomes nearly as accurate as the i1Pro but has those the two important advantages I mentioned.
I haven’t seen specifications yet, but if the C6 is anything like the the C5 I’m guessing this will be a great little meter for the price.
Best,
Greg
