Palminfocenter is reporting that there has been a update to Google Maps for the Treo. "On the Google Mobile Maps Treo-specific page, Google hints at speed enhancements in this latest version, along with real-time traffic reports and detailed directions. Google also touts "shorter startup time" and "stylus integration" as enhancements in this latest version of the app." I tried this on my Treo 750 and it does seem to be somewhat quicker and I still believe it's one of the best programs available for your Palm device.
