What is the range of the radio? Is it greater or lesser? I am wondering whether the switch to a USB dongle has any big significance other than a smaller footprint.
How robust is the new radio? Most USB sticks aren't very strong against sudden jerks and may end up randomly breaking!
There is an ethernet port on the RoboRio. If you need to, you can include an ethernet hub on the robot. The plan is to move towards USB for stuff - for example, it's a lot easier to obtain cheap, good performing USB cameras than it is to get an ethernet one.

The range of the radio seems adequate - we haven't done any specific range testing, but it covers our build space and the entire field FIRST had set up during the Alpha Test weekend.

The radio is a typical USB dongle. We connected it through a USB extension cord, which let us attach the dongle with velcro to the same place we had the dlink. Since it's so lightweight, even with a hard hit to the robot there's really no force on the dongle itself. I don't recommend sticking it straight into the RoboRio and having it buried inside the robot!
