Let’s face it. People aren’t really that welcoming towards redesign, if given a choice, they probably would choose to have the business as usual. And aesthetics matters only to certain degree, and if it stands out it becomes distracting. I wish people consider that familiarity should be an important factor in considering whether to change UI or not, UI can be good if they choose to look unimpressive, for utilities it might be better that way.
And real world appliance really changes the design so dracstically as software, a micro-oven looks like a micro-oven, a Coca-Cola can looks like the same like forever. A car always has 4 wheels. Why on earth software just changes the information flow randomly just because they can? This doesn’t make sense.
