Suggests SD card slot, no USB
A Japanese site is displaying photos of what it claims is a realistic mockup of the second-generation iPad. Allegedly encountered during a trip to Shenzhen, China -- home to many technology companies, including Apple manufacturing partner Foxconn -- the mockup is notably thinner than the current iPad, and also uses tapered edges, similar to those on the fourth-generation iPod touch. The back is otherwise completely flat, doing away with a previous bulge centered around the Apple logo.
Also visible on the mockup is a larger speaker grill, and a hole for a rear-facing camera. On one edge of the tablet is an alleged SD card slot; there is said to be no evidence, however, of a secondary USB port. The front of the mockup assumes the existence of a FaceTime camera.
Apple is expected to formally announce the second-generation iPad during a March 2nd press event. Aside from twin cameras and a possible SD slot, the upgrade may include a dual-core ARM processor, a dual-core graphics chip and a hybrid HSPA/EVDO cellular receiver. Considered unlikely at this point is a Retina Display, as the technology may be difficult to mass-produce at a 9.7-inch size.
