A bit of a stink has errupted over the weekend as more and more ASUS Transformer Primes finally started getting into users' hands, and said users discovered the bootloader is locked down tight. That really shouldn't be a surprise, and the suggestion that ASUS partook in false advertising for not mentioning the bootloader on the box is, at least, ridiculous. (For what its worth, the review unit we received wasn't locked down.)
But fear not, intrepid tinkerers. On its Facbeook page, ASUS has said it's got an official statement coming up. "And in the meantime, relax." That's probably a good sign.
