How do you know what great design or technology is?
The more you use it, the more you like it!
The more you use something, the more the design surprises and delights you in ways you couldn’t have even imagined!
For example, the iPhone Mini: the joy of shooting photos with one hand, the ability to reach all of the screen with one hand, and even the ability to use the phone with my (less dominant left hand)! The thought that ‘one handed photography‘ is great!
