If you're jonesing for a netbook and you live in the States, Sprint and Best Buy will sell you one for the low, low price of 99¢.
...
The catch is that the netbook - a Compaq Mini 110c-1040DX - must be purchased with a two-year Sprint 3G wireless-broadband service contract that runs $60 per month for 5GB of data downloads. Add to that $1,440 the sales tax you'll need to pay on the netbook's $389.99 list price, and you'll be shelling out just south of fifteen hundred bucks.
...
If the Sprint deal doesn't attract you, Best Buy will hook you up with AT&T or Verizon instead, but they'll charge you $199 up front for the hardware.
AT&T offers a 200MB-per-month plan for $40 - that'll run you about $1,160 over the two-year contract. The company also has a $60/5GB plan, plus other plans that include subsidized netbooks.
Verizon's entry-level 3G plan gives you 250MB per month at $40 and matches Sprint and AT&T at $60 for 5GB. Verizon is offering its own netbook-bundling plan, but if you want to skip the netbook part of the deal they'll be happy to set you up with one of a half-dozen 3G cards and dongles.
