The Sprint Novatel Merlin C777 is a 2-in-1 broadband card aimed at users who prefer or require older model cards. Since it utilizes either your computer’s ExpressCard or PCMCIA card slots, it frees up USB ports for other devices.

Other key features are an external antenna port for getting better signal and official support is available for Windows 2000, XP, Vista, Mac OS X 10.4.11 (& higher) and Linux. explains the difference between an ExpressCard and PC Card. The beauty of the Merlin C777 is that it’s both (thanks to a PCMCIA adapter).


Stuff You Should Know (Good & Bad)

Design & Aesthetics

Like most ExpressCards & PC Cards, the Merlin C777 extends less than an inch past your laptop when inserted. This gives it and other cards a natural advantage over USB broadband cards since it’s harder to break if something bumped into it.

Weighing in at 1.65 ounces, it’s just a bit heavier than a slice of bread. Pretty light stuff. Also, in it’s PC Card form, it’s about 2.1" wide (a bit smaller than a Blackberry Curve 8900) while just over an inch in ExpressCard form (just over half the width of a credit card.

While I wouldn’t recommend it for turn-by-turn navigation, it can be pretty handy if your tire blew up on the interstate while going 80 mph and you needed to locate the nearest town to tow your car to.
