more thoughts on the new mobile: The worst feature by far (ignoring being forced to use one carrier) is the glacial molasses-in-January EDGE wireless service from AT&T. Don't even think of using the web browser using EDGE unless you have pressing needs to see one page (I'm talking about 1-2 minutes for a NY Times page to render). Performance in WiFi is spiffy - so it isn't the device. If you really need on-the-go web, forget this until a 3G alternative arrives. (Via tingilinde.)
EDGE seems to compete with other network uses in a really bad way. On my T-Mobile data service I sometimes get decent Web performance, but it becomes useless at busy times in places where there are a lot of calls going on, for instance airports. Packet losses of over 50% and ping times of over 5 seconds are not unusual in those situations.
