I think the Google bicycle thing is a definite pre-beta that should have waited a bit until unveiling. At the same time, eventually Google will aggregate and refine this to the point to which ACA maps are unneeded, except by those who want all the services/hotels, etc. listed on them. Hard to guess the timeframe, but at some point these online maps will combine with electronics leaving 95% of tourers hard-copy map-free.

And I say that as someone who really likes maps, esp. the hard-copy ones.
