iPod

It’s a bit ironic that Apple is the favorite tech brand among tree-huggers when you’ve got thousands of users tossing plastic cases into landfills so they can get the same case with a bigger drive or a different screen. Made modular, you’d be able to buy an upgraded disk, display, or firmware without tossing everything else. That white box would also be green. How do you like them apples?

Automotive

The same should be done with cars (which we Americans toss far quicker than anyone else). Designing a car that let’s you upgrade body and interior panels would save thousands of tons of steel each year, just for that line. Consumers would get a fresh look that’s more personalized, companies could cut back on production and shipping expenses (seeing as they’re losing money on each new car, it’d be a relief to profit on new panel sets), and consumers would be willing to spend a little more on technology and comfort features, knowing the car will still be in style (their style!) ten years down the road.
