True Multifunction

While there are a number of specialized scanners out there, and a lot of photo printers, sometimes it's good to remember that you don't necessarily need a business card scanner to scan business cards, or a 4 x 6 photo printer to print good photos. If you have a solid, high-quality all-in-one, for example, you can use that to print good photos (as long as you have the right paper), scan business cards (although you'll have to place them manually on the scan glass), and do a number of other things. And you don't have to buy -- or store -- a bunch of other devices.

In other words, while specialized tools are often really convenient, sometimes a multi-function tool is the best way to go.
