Over limit fees for Sprint and Verizon Wireless are 0.05USB/MB - so I figure AT&T should be competitive.
Great use for netbooks. Mobile road warriors who are given a corporate netbook that is locked down and for email/connecting to a corporate database will find 5GB decent. Sure, you can't watch netflix every night (went on a 1 week vacation and burned through 3GB watching 3-4 hours a night for 5 days).
However, just try to make me get rid of my mobile broadband. Anywhere I want to go that has cell phone coverage, and I get internet. Great when traveling to look at lowestgasprices.com, weather.com, and so much more. Full browser is easier to use than Opera mobile or Skyfire. Netbooks may have wimpy processors, but they are much better than what you get in a smartphone.
Finally, don't forget AT&T customers get free access to wifi hotspots. So, you really only need the mobile broadband in a pinch.
However, I'll skip this. I have my cradlepoint PHS300, and since 2.3 it works with my omnia. Nothing like being in the car and letting a bunch of friends look up on the internet things to do while traveling (or check their email, or whatever). I don't mind paying a premium for the convenience - after all, I don't make my own butter and eat out sometimes at restaurants because it is convenient!
