What separates really well-designed stuff from merely handy things is that we often don't realize we needed it. It's like someone anticipated needs we didn't even know we had.
It's amazing just how much well-designed stuff is even out there. For all the junk that litters our lives, there's just as much that has real thought behind it — but we could still use more of it. The good news is that things are always evolving, and it's only going to get better and better.
