A gyroscope is an ancient navigational instrument that aims at keeping the platform of the magnetic compass exactly horizantal no matter at what angle the vessel surface tilts to amidst lashing water currents. Well, Apple’s Iphone is the first one to feature with a digital gyroscope, which however, doesn’t stand to the expectations of the iPhone fans! This one has indeed turned out to be an excellent concept gone waste. If you take a look at the video, the indicator ring just runs towards any corner of the screen the phone is tilted towards. I really doubt if this could be indeed called as a gyroscope!
