In a note to investors on Wednesday, RBC Capital Markets Managing Director Mike Abramsky reiterated the firm’s confidence in Apple’s upcoming next-generation iPad. RBC predicts that Apple will sell 30 million iPad 2 units between April 2011 and March 2012. Apple will unveil the iPad 2 at a media event next week, and the tablet is expected to launch in late March or early April. Abramsky discusses expected hardware specifications for the iPad 2 in his note, which include a faster 1.2GHz processor, 512MB of RAM, a rear camera, a front-facing camera for FaceTime video chat and a thinner, lighter case. He also notes that initial supply may be constrained due to component availability, however, which jibes with our earlier report.
