We have a Cr-48, and we've used the 3G several times. The monthly caps get you surprisingly far, if you're doing simple things like GMail and Google Docs. And when we've needed it, we've used the "unlimited for 24 hours," which has been fine. It's a tad pricey. I mean, the 3G in the Chromebook is NOT going to be your new ISP. You will continue to use WiFi the vast majority of the time. But every now and then, you won't have WiFi. 3G to the rescue. My wife used it last year, while we were driving cross-country, to watch Youtube videos for class, write a paper for one of her classes, and apply to summer educational opportunities (on a web page with hundreds of questions). Without the 3G, we would have had to NOT DRIVE on our trip, which we also needed to do. We would have had to buy a 3G fob from Best Buy or Verizon, or sign up for tethering the phone with Verizon - both of which are MORE expensive for the one or two times a year when you really need it.
