Apple has launched the Apple Watch to much fanfare and positive early reviews. However, this collectinon of gadgets were also highly anticipated before becoming major flops. First up is Apple’s earliest foray into mobile computing.

Long before the Apple Watch, iPhone or the iPad were on the scene, in the late 80s, Apple launched the Newton PDA. In total the project cost Apple $100m but this was never rewarded with strong sales. In the end the project was cut, to be revived in spirit – if not hardware or software – when the iPhone and iPad emerged many years later.
