We just got a couple of these
modems in for testing with our systems and they are the coolest. Unlimited wireless access for about $90 per month, about 64 kbps on a consistent basis. All in all, not bad.
The unit sticks out about 1" from the PCMCIA slot, which is no big deal, really. We allegedly have coverage in Sprint's entire footprint, which is ok in major metro areas. I have not used Sprint's phone services, though I have seen plenty of negative criticism. We'll see how reliable this is. For now, it's the coolest.
