I guess this would be good for those not wanting to shell out for an iPhone and service from AT&T. Had I had a choice between the iPhone and Touch when the iPhone came out, I still would have gone for the iPhone. I need the EDGE connection no matter how slow. I'm out a bunch of the time, and WiFi is hard to get a hold of ... unless you are at home or in the office.
As for Google Maps, you can still visit the webpage. And same for email.
