you know I thought this was a, can't say the word I want, complete joke when I first heard AT&T got it. But then I look at these plans, they really aren't that bad, considering I was thinking this would cost close to $50-$100 for the same amount.
These are also the contract, so it's kind of like buying one of those prepaid cards. If rollovers offered, I could see reason why not to get a 3G version. I have over 50Mbit download and 5mbit upload and a wifi in the home, so I don't need 3G there. Let's say have to visit a relative, or worse yet I have to go far far away from normal technology, I still get a signal just a Wi-Fi. I could see shelling out $15-$25 so I could use the Internet. Granted I wouldn't be streaming movies, I can keep in touch with every website a visit probably for full month on the 250 MB plan, if they allow some kind of ad/image/flash block.
keep in mind this is pretty much for emergencies only.
