Yes, an old acquaintance of ours, already used to illustrate several articles on the subject:
The information AppleInsider, who says he talked to sources close to the creation of iTablet. According to them, the touchscreen Mac would resemble the mockup above, but it would bring some extra elements of the first generation iPhone.
The article describes the design of the iTablet as made of aluminum (under construction unibody), even thinner than the iPhone itself. It would come with connections such as those on the iPhone 3GS: 3.5mm headphone jack, built-in speakers, microphone, GPS, 3G and 30-pin dock connector. The 10-inch display would be surrounded by a black border, just like iMacs.
What do you think?
