Wouldn't it be nice if there was one universal power supply for every electronic device we owned? Devices these days like cellphones and laptops automatically come with a power adapter to convert AC power to device-specific DC power, and they're always different from one another. This causes a lot of waste when people decide to get rid of their devices and the adapters end-up in a land-fill.

When we think of people who are lacking computer skills, we can't help but also think of people who are lacking car repair skills. Both groups of people can be at an extreme disadvantage because of their lack of knowledge if something were to go wrong with their computer or their car.
