Conclusion: If your business currently supports Treo 600s or other palmOne PDAs for your mobile workforce, or if you finally are giving in and buying a smartphone, the Treo 650 is a compelling upgrade that makes it a must buy for all but the most bleeding-edge power users.
Pros: Many improvements over the excellent Treo 600, including high res screen, improved camera, removable battery, Bluetooth. Non-volatile memory can save your PDA data even if the battery runs out.
Cons: Could use a little more RAM as well as Wi-Fi. Lackluster speakerphone performance.
Conclusion: Looking for a convergence device that gives you the best of both worlds? The Treo 650 should be on your short list. While larger and heavier than today's feature phones, you won't have to carry two devices so you'll ultimately lighten your load. The phone has great looks and ergonomics, a thumb keyboard that makes real work possible and fast Internet access courtesy of Sprint's PCS Vision service (CDMA) and EDGE service with Cingular / AT&T Wireless (GSM).
Pros: Great display, fast performance, integrated Bluetooth, good battery life by smartphone standards. Battery is user replaceable, uses non-volatile memory so data and applications will survive a complete battery drain. Doubles as an MP3 player and portable video player. Expandable via SD cards.
Cons: No Bluetooth DUN profile on carrier branded Treos (but one is coming, we're told), no WiFi and the only way to add it is via Enfora's bulky sled. On the Sprint version, there's and odd delay of a few seconds after pressing the send key to dial a number (doesn't happen on Cingular version). A high end device like the Treo 650 should have more internal memory. Given that the unit doubles as an MP3 player, why is a mono rather than stereo earbud headset included in the box?
Summary: Lately the line between cell phone and smartphone is getting very blurry. The typical phone sold today is more powerful than ever and has a number of features that used to be exclusively in PDA territory like an alarm, daily planner, and MP3 player, but they still do not have the power or usability of a PDA. The Treo 650 functions as a cell phone, but does not have the limitations of most smart phones- it is a fully functioning PDA also.
Excerpt: Jin Khang gives us a review of PalmOne's Treo 650, a device that Jin claims is much improved over the Treo 600 that it replaces. While it might not have a megapixel camera, it turns out to be both a good phone and a good pda.
Excerpt: How would you like to carry one device that serves as a camera, cell phone, MP3 player, emailer, instant messaging unit, and PDA? Now you can employ all those functions in one with palmOnes Treo 650 ($599 with calling plan), an upgrade of its do-it-all Treo 600 that packs even more power while boasting better usability. This fourth-generation smartphone shows that its possible to be a jack of all trades without being a master of none.
Summary: Check the price and contract details in the new year, as this will not be a cheap phone (probably selling for something like Â£380 the 600 currently sells for SIM-free). Expect this to be a reliable replacement for a trusted performer.
