Admit it. Back in 1984, you chuckled when you saw the advertisement for the Apple Macintosh 128k computer. Who would blow $2,500 on a beige plastic box with a keyboard? What on earth would anyone do with a personal computer anyway?
Fast forward to today. You've read about 3-D printers. You know they're all the rage with the geek squad. You may even have seen today's news that Home Depot Inc., the world's biggest home-improvement chain, plans to start selling them. You're not entirely sure what you'd do with one. But can you risk getting left behind -- again?
