    While I can understand that there can be some customization (different
    coloured facias), logos (Cingular, Verizone...) and custom applications
    (Xpress mail...) why are there so much variation in palm products both
    feature-wise and performance-wise?

    I'm basically asking, how can there be differences in volume or modem
    performance in a mass produced product like the Treo 650. No, these do
    not
    appear to be variations in manufacturing, but actual, identifyable
    differences based on carriers, phone branding etc. Even allowing for variations
    between CDMA and GSM?

    Makes the whole palm operation look like a cottage industry.

    This, I am writing with reference to the following, posted elsewhere on these forums:

Only Cingular's expensive data plan makes us hesitate to recommend this model over the Sprint version.

    As a phone, the Verizon Treo's sound quality is impeccable, with a clear speakerphone 12 dB louder than that of the Sprint version."

    The verizon model has the best phone radio....the sprint the cheapest data plan....that's why Sprint models are always gonna need VolumeCare.
    Game over!

    Each carrier has input into their version. . . . . .and I believe the Cingular version was a full 5 to 6 months behind the Sprint . . . . . differences can and will occur.

    Just look at verizon demands...what with all the feature disabling they do with their phones. If memory serves me right, they even lost a class action suit due to bluetooth crippling.

    Don't believe everything you read. A few points:

    The GSM phones have better battery life simply because they are GSM. EVERY GSM phone has better battery life than a CDMA phone that is otherwise identical. GSM simply uses power more efficiently. OTOH, GSM is prone to causing interference with other radio devices, hearing aids, monitors, and more. And the GSM Treo has much higher levels of radiation than the CDMA phones. In fact, the GSM Treo was one of the worst phones in this regard. So you pays your money and chose your trade-offs.

    Similary only GSM phones have EDGE because EDGE is a GSM only technology. A CDMA phone can't work with EDGE. The CDMA equivilent is EvDO. Why don't the CDMA 650s have EvDO? Probably because Sprint and Verizon weren't interested in supporting it at the time the 650 was designed and released, because their EvDO networks were not very widely deployed. And remember, Palm's real customers are not you and me. Palm sells products to the phone companies, and THEY determine the specs. The 700P prototype that's been seen here on TC has EvDO, as does the 700w.

    Oh, as far as performance, EDGE frequently isn't as fast as it's proponents claim. In some cases, not much faster than the CDMA Treo, and quite a bit slower than EvDO.

    Finally, let's talk about volume. Ain't no way the Verizon Treo 650 has a speaker phone 12db louder than Sprint. The decibel scales is logarithmic, and a 10db increase is twice as loud. I've got a Sprint 650, a recent co-worker has a Verizon one. Speakerphone and earpiece volume on the two are very comparable. If the Verizon one is louder, it's only slightly, not more than twice as loud. I have no volume issues with my 650, and I've never used volumecare. (OTOH, the speaker on the back of the 650 is easily overloaded, and distorts, if the volume is turned up too high--and volume care would only make this worse).

    From my reading of these forums, those with the biggest complaints about volume, and those most likely to use VolumeCare, have been GSM customers. Maybe that's one of the trade-offs for longer battery life?

    Again, just to emphasize: Palm's customers are the phone companies. Aside from the differences directly related to technology, a lot of the differences reflect the desires of the phone companies. Other's reflect the fact that they really are different phones, with completely different radios, on the inside.

    In fact, my understanding is that EDGE is roughly equivalent to Sprint's 2.5G data network used by the Sprint Treo 650, with the Sprint network even outperforming EDGE somewhat (and/or sometimes). Ev-DO is a much faster network used by the CDMA providers (Sprint and Verizon) and blows EDGE out of the water. Only the WM5 Treo 700w supports Ev-DO with the upcoming Palm OS 700p also rumored to support Ev-DO. GSM's "equivalent" to Ev-DO is UMTS which is slowly being rolled out in the US by Cingular.
    Now THIS is the future of smartphones.
