> For example, the microwave. Older microwaves have a cumbersome enter time, hit start procedure. Newer microwaves also have a "quick start" button for 30 seconds which you can just press four times to get it to go for two minutes, or enter the time if you need it to go for a while. Hardly the stuff most people will replace a microwave for, but definitely a feature expected of newer microwaves.

How old are we talking about? My microwave is exactly like that, and it is about 15 years old if not more.
