The site 9to5mac claims to have obtained industrial schemes of molds which will allow the accessories manufacturers to manufacture the cases for the iPad 2. If we can distinguish a reserved location a dock connector located on one side of the device (which therefore confirms the rumors on this subject) , we can also see that the new machine would be finer on the sides, like the forms used for the new iPod touch.
More precise details are also revealed since we can discover dimensions like the thickness of the device which would be more than 8.5mm (presumably in the center of the machine) against 13.4 for the first version.
Finally, and this is the most crisp, the presence of a new port / connector located on the left side of the machine. Could this reveal the presence of an SD card reader or a USB port? Rumors in recent months have been rather insistent on this subject.
The fact remains that even if this information is becoming more and more precise, it remains to be taken with tweezers.
We discuss it on the forum.
