there's a convenient way to connect to EV-DO networks with a laptop that doesn't have a PCMCIA slot (like, say, 12-inch Powerbooks
). The CCU-550 from Korean manufacturer
CMOTech looks like a basic USB flash drive, but is actually an EV-DO modem with maximum throughput of 2.4Mbps.
Unfortunately, you'll need to live in Korea to use it. Sure, you can try to import one to the US on your own. But
without the blessing of your service provider (meaning Verizon or Sprint), this is just a pretty paperweight.
