For true “broadband on the go”, most cellular companies have been offering plug-in 900Mhz cards that allow you to use your cell phone provider as your ISP, wherever you have cell service. Motorola
is looking to please Mac users lately with the release of the Mobile Connect 3G Datacard
for Macs. In particular, though earlier versions work with desktop Macs, the notebook users were left out due to the lack of PC Card support on MacBook Pro. This new version will use USB, and supposedly gets the same speed as the other cards at up to 1.4mbp/s, impressive for cell networks.
