If Amazon can do things for maps like it did for file storage(s3), it would be phenomenal for developers , as most of the innovations in recent years depends on location data.
It should not be too costly for Amazon to provide maps and geo data. They should make map services part of AWS.
I doubt it will be that cheap, at least to implement a fully fledged service alla google maps. But sure it will be interesting for a lot of developers.
Amazon builded AWS out of necessity and then transformed it into a public service.
I believe it make sense to them to build a map service in the same way, giving they they are still a logistic company it could be more than helpfull for them.
