The only improvement on the new models is the inclusion of built-in 3G. The software, from all signs uncovered in the Dingo release, will be the exact same as what we have on our eDGes now. Since most campuses have wifi, as do coffee shops, airports (even my local car dealership out in the boonies), 3G will really be of use only for those that can't find a wifi spot when they really need one, on a regular basis.
