Sprint EV-DO

Right now, Sprint is offering a sweet deal. Free wireless PCMCIA cards (after $150 instant rebate and then a small mail in rebate). With unlimited access at $59 a month and a very high speed wireless network, it's worth checking out. Much better deal than Verizon, who doesn't give you a free card and charges something like $80-90 a month for "unlimited" access. Verizon's package is not really unlimited though, because you get like 5 GB of transfer before you are cut off according to the TOS and you aren't allowed to use the connection to do anything but download simple HTML pages (therefore, if you are doing more than their monthly transfer limit they immediately cut you off saying you must have been downloading music or some other activity that violates the TOS).

It's not quite fast enough to replace your home network yet, but it is pretty darn fast and great for getting some work done on the road like I am right now :).
