It definately sounds as if this would be very nice for chasers to have. Especially those who use laptops are their primary source of data while on the road. Once the price gets to an area where the average net user can afford, I'm sure it'll add some options for those who can't afford the likes of WX, Baron, and those types of specialized services. Even if access is limited to cell phone coverage, the ability to get that kind of information on the fly as opposed to having to stop at a WiFi station would definately make for good results; especially for people like me who may spend a great deal of time on interstates getting to the day's target (driving from Denver or far off places to get to other far off places).
Obviously cell phone service is severely limited in rural areas, and obviously this type of service may have different bounderies, but the prospect of having on the fly WiFi-type internet on the road would be an incredible tool for us budget chasers!
