Perhaps a better competing use for a $25 Raspberry Pi is Apple's Airport Express ($99 retail). I would love to make every one of my USB peripherals be decoupled from my computer. Printer, scanner, external hard drive, etc. All you'd need to do is a $10 USB Wifi dongle, slap it into an enclosure, and resell it for $75 as a more customizable Airport Express. Bonus points if it prints from and scans into my Dropbox or Google Docs.
