Which one is the working Due version?

ESLEagleEye:
I think a missing crystal is a huge difference. Especially for people who wanted to use the SAMs RTC.

Yes, well if they added the crystal I'd have to agree that it makes a difference, but they have removed it so there will not be any support for using it. Has someone actually gotten a board with the crystal? If then it's just a very small number of boards that has it.

(Don't get me wrong, I'd like the crystal too. But I'm sure they had their reasons for removing it.)
