#1: BookEndz BE-MBP13SD
Are you a musician? A business person? Or maybe just someone who has to take their laptop with them a lot, but as a lot of external devices that they use at home. Until now, bringing your laptop somewhere meant unplugging all of the devices you had attached to it (printers, scanners, keyboards, mice, MIDI devices, etc), letting the cords sit there, and then replugging everything back in when you got home. It was a hassle, to say the least, but not anymore thanks to the BookEndz BE-MBP13SD.
I know I sounded like an infomercial just now, but I'm serious: If you attach things you your computer at home that you don't bring with you on the road, you'll want to buy this. How it works is simple: When you set your laptop on it and close the latches, it re-routes all of the ports (audio, USB, ethernet, etc) into a back hub that you can plug all of your devices into. When you want to bring you laptop someone, just fold down the latches and bring it with you all of the devices stay plugged into the dock itself, so when you come back all you have to do (once again) is set your laptop into the docking station and turn it on.
It is, most certainly, the handiest device on this list, because it essentially turns your laptop into a desktop computer that you can take with you should you so desire. Pretty awesome if you ask me. And the price? A little steep at around $230, but nothing that isn't worth it.
