Techinch, March 2011:

Looking just at the specs, a microwave didn't make sense to many. So manufacturers bundled them with cookbooks that detailed the many things you could cook in a microwave. Look, you can make this great Chinese dish in a microwave! Our microwave lets you bake a cake! Need a hot cup of this complicated spiced cider? It'll only take 15 steps in our microwave! They thought the microwave needed to be a full oven, and more.

But, wonder of all wonders, people started buying microwaves and using them regularly. In the store, a microwave didn't seem like a must-have item to many, but once you incorporated it into your daily life, it was irreplaceable. [...]

The microwave isn't easier for every cooking task, and perhaps it takes longer to prepare a complicated meal in a microwave. Perhaps no award winning meal will be created in one, unless it's a special contest for microwave cooking. But it simplified simple cooking, and consumers around the world saw it as a necessary piece of equipment within in years of it becoming popular. It didn't need to be an oven, and didn't need to be better than an oven. It just needed to be the best for some certain cooking scenarios, and that was enough to win the hearts and minds of people around the world.

Last year, Apple introduced the iPad, a computing device many have struggled to classify. It's bigger than a smartphone or iPod, smaller than a computer, but can do some things you'd otherwise do on both of these. You can type a document in Pages or find your way with GPS and Google Maps. So what makes it so special? From a specs perspective, tablets don't make sense. It cost just under $500, but if you've already invested in a computer and a smartphone, it's just another expense. Plus, netbooks only cost $300, right?

In 10 years, young adults will look at the tablet the same way we look at microwaves.
