I liked my 7520 and my free incoming, but that thing is giant and I wanted faster internet. I am in the process of switching my users out to t-mobile. And we are Gov. I too started switching in Dec when it became apparent that Nextel wasn't going to be coming out with the 8700. I am now on an 8800 and loving it. I still have a few hold outs, but I will eventually pry their 7520's from them
