The 600 has the exact same cpu, screen and the rest than the 700, they just installed a different "Operating System" on it. (I know, it's not actually a change of OS but the analogy stands)
..and again how is that a downgrade? if as said they are basically the same..
yes the 700 had side lights but it was the lights that led to bad screen contrast.
Anyway, I hope its true that annotations is just a firmware issue so people can get a firmware update or find a way to switch "operating system".
