Based on our own professional squinting ability, there are USB plugs on the left and right sides, Mini DisplayPort and an SD card reader on the left, and a power plug on the right. Of course, since the screw holes are facing us, we're probably looking at this from the bottom, so flip all of those around if you want to imagine using this thing (because, of course, the power plug will be on the Apple-standard left side). We also have it on good authority that the rest of the machine has been restyled in modern unibody style, including the large single mouse button, but that the screen is still like the current MacBook Air, instead of the edge-to-edge glass with black edges. Also, it's apparently running the same Core 2 Duo SL9400 processor of the current generation MacBook Air -- possibly further proof that this is a very early prototype (our source says the model dates back to at least April). We're working on getting more images and information, but for now at least two things seem (relatively) clear: Apple hasn't forgotten about the MacBook Air, and 13.3-inches isn't going out of style just yet. Hopefully we'll know for certain next week!
