Needless to say, all of this will remain strictly within tablet territory, and the dimensions of length, width, and thickness point to it being 305.7mm x 222.6mm x 7.2mm, and if that were to be translated to inches, then it would be 12” x 8.7” x 0.28”, respectively, which has more than enough space to cram in a 12.9” display. There does not seem to be a side-facing port in this particular leak, however, which has been touted by some to be a second Lightning port, or perhaps a USB-C connection. Right now, the 12” MacBook happens to be the sole Apple device that supports USB-C connectivity. Needless to say, it is wise to take all that you have seen with a pinch of salt since this is but a rumor.
