The Treo 650 is both a cell phone and a full-featured Palm OS PDA. The Sprint version runs on their CDMA network in the US and supports PCS Vision (1xRTT for high speed data). While most mobile phones with full-featured PDAs make concessions to phone ergonomics or PDA ergonomics and features, the Treo manages to do it all and do it well. It's easy and comfortable to use one-handed as a phone and has all the features of a current generation Palm OS 5 PDA. The integrated thumb keyboard makes it a great choice for those who need to write emails on the go. Though larger than today's feature phones, the Treo is still pocketable and smaller than competing Pocket PC phones.
