Goldman Sachs analysts have claimed to have some details of Apple’s next-generation iPad. According to them, the next iPad is expected to have at least one camera, a lighter design, 9.7-inch display, and (surprisingly) a mini USB port. If the speculation is accurate, then this new iPad will begin to ship early in the spring of 2011. While recent reports hint that the 7-inch model is almost ready for prime time, the analysts claim that the device isn’t finished and might not necessarily be unveiled at the same time. Foxconn will also continue to be the manufacturer of the device. The rumors might seem believable to some, though you can bet that many will question the authenticity of the mini USB port claim, since Apple seems heavily in favor of its own Dock Connector at the moment.
