M-UX was added to the global N10.1-14 microsite about a week ago as a feature. The eBay seller just copied<>pasted the info in to his listing. SamMobile already has posted a Tab|Pro 10.1 ROM and a Note|Pro 12 ROM for download and they aren't even on sale yet. When a N10.1-14 ROM with M-UX appears it's pretty safe to say they'll post that too. So the N10.1-14 in that listing is likely no different than any other N10.1-14. And a buy-it-now price of $999 for a SM-P605 is just plain crazy.
