The Mvix Nubbin protrudes less than 2cm from your computer as it adds 802.1n Wi-Fi to your computer, making it the world's smallest Wireless-N adapter. It's also competitively priced at $40.
Compatible with PCs and Macs, the Mvix Nubbin can be used on 802.1b/g/n networks despite its stature of just 3/4 of an inch. I'm ever so skeptical about the Nubbin's ability to ferret a weak signal compared to its larger brethren, but I'll give the little guy the benefit of the doubt while adding that it ships tomorrow from retailers around the web.
