The iWatch might be on its way, but at least one analyst believes it will arrive later than expected. Apple’s proprietary foray into the wearables sector may not come as quickly as we originally thought, but is still expected to arrive by the end of the year. Why the delay? Apple may be trying to do too much with their wearable. Information from KGI analyst Ming-Chi Kuo notes issues in just about every part of the process. Hardware, software, you name it, Apple is having problems. The screen, which some believe will be AMOLED to help control battery life, is said to be covered in Sapphire glass. According to the analyst, the implementation of Sapphire glass is giving Apple fits.
