What is an Aircard?
Mobile Broadband cards (or aircards), are small sleek devices that plug into your laptop. They allow you to access wireless broadband on cellular networks and come in 3 main forms:
(1) USB
(2) PC Card
(3) ExpressCard
USB cards plug into the USB slot of your laptop or PC. For
this reason, they are usually the most compatible with wide ranges of PC's and
Mac's.
ExpressCards are the
next generation of PC Cards. Slimmer, smaller and compatible with Mac's, most
providers offer these.
Which kind of broadband card you get depends on your needs. They all pretty much do the same thing. The
differences they have lie in nifty features they may have. For more details

Broadband Exposed". There's an entire lesson dedicated to picking the right
aircard.
