Google Maps definitely made traffic-based time estimates for routes and (AFAICT) also made route choices based on traffic before the Waze acquisition, though its traffic data has gotten better since the Waze acquisition (particularly, it extends to more non-freeway routes) and it has more information on the source of traffic problems (which appears to be largely directly because of Waze, since it credits information to its source and "reported by Waze" seems to be by far the most common source of most kinds of reports).
This is true, Google Maps definitely has done traffic avoidance for years, even before the Waze acquisition. I think prior to Waze it was a completely self-contained reporting system though (other people using Google Nav on Android were automatically/anonymously feeding their speed/route back to the homebase and that was used to detect traffic anomalies). Presumably they now have more data to work from.
I've been an embedded user of google voice since it was grand central and tried to move over to android, but that OS seems to be a bigger mess than Windows Mobile phone. It's a bit ironic that the people who love it don't really do anything on their phone, they don't use the "openness" android supposedly gives. With Jailbreak, IOS is pretty amazing.
