It is understandable that an additional speed sensor would be useful for a trainer.
I guess that I am just disappointed. I want downloadable maps, not just trace routes. Trace routes are OK for hiking or running because your range really isn't all that great. However, for cycling, it would be very nice to have robust mapping capability. But I guess this is how Garmin differentiates their training products from their mapping products.
It may interest you to know that with motionbased.com (which I think is somehow owned or partnered with Garmin), you can export Google Earth routes. Not quite the same as a map, but depending on your need, might be useful.
