I'm not sure why you'd want to use such a wireless mouse receiver with a computer that has bluetooth built in?
Also, I haven't plugged in a printer in years. Many printers have Wifi built in, and if not, you can always attach it to an Airport base station.
External storage? Use Apple's Time Capsule or any other NAS to back up your data wirelessly.
I've even seen companies use Apple TVs connected to a projector for wireless presentations.
Sure, a USB thumb drive is invaluable when you need to copy some files to your uncles 10 year old laptop with broken wifi; but you can get pretty far without wires if you want.
