I have several other Garmin Nuvi GPS devices that are smaller and do not have the MSN features. All are excellent GPS devices and have become essential in finding meeting locations and baseball fields where my son plays, especially when the directions provided by the other coach are flawed or sketchy. The 680 is larger and easier to see, but the best addition is the MSN traffic. We live around a large metropolitan area so it is helpful and has already allowed me to avoid certain roads because the Garmin indicates there is a high traffic volume. If you live in a remote area of the country it is not much value. All in all I would prefer this device over the smaller 350 and 360 because of the bigger screen. It is not heavy though so it can still be carried around for walking tours.
