The article talks about EvDO and HSDPA. I don't know how those relate to EDGE (I've only got about 0.1875 of a clue about this so far, if that much).
I'm already using NAT with my dialup, but at least the (dynamic) IP address of my gateway machine is visible, which is how I can telnet/VPN to it ... I can see the disadvantage to not even having that exposed, but I mostly use it to access my house from elsewhere, so if I were carrying a do-everything laptop, I'm not sure how much it would bother me. (OTOH, it's a good reason not to use it as the main Internet connection for a stay-at-home machine, and blocking VOIP would certainly be an issue unless I could use it as a conventional cell phone at the same time as I had a data connection going.)
