Best Wireless Network Adapter?

So here I sit, my completed build in front of me, when I finally realize I forgot to buy a wireless card/adapter. I guess I assumed the motherboard had one installed, but regardless, I need one now.

I think I'm leaning towards a USB dongle rather than a PCI/e card so I can 1) use it with other devices if need-be and 2) save space in the case.

So I'm open to suggestions. I've been eyeing this one: http://www.amazon.com/TP-Link-TL-WN822N-Wireless-Adapter-Antennas/dp/B00416Q5KI/ref=pd_cp_e_0 but before I pull the trigger I'd appreciate any input.

Thanks!
