MiFi devices have risen to prominence over the past year or so. Unlike the typical USB dongles that serve mobile broadband directly to your computer, a MiFi creates a short range Wi-Fi network. The advantage is that multiple devices and computers (usually up to five), can simply connect via Wi-Fi. This eliminates the need for cumbersome mobile drivers, since they work on standard 802.11 b/g wireless protocols.
It might be passe to bash AT&T's coverage capabilities at this point, but, with its track record of poor service, we're questioning who would select AT&T as a mobile broadband provider versus the viable MiFi devices already on the market from Verizon and Sprint.
