The phone reflects (largely) the kind of good product management we've seen from Palm over the years-- this one has all of the bells-and-whistles you'd expect in a Treo. However, there are a couple of points that seem an entire lapse in judgment.

The battery life is terrible. I've read all the various comments about how to improve it, etc., including the snarky ones about "putting it down for 2 seconds". Bottom line: the battery life is WOEFULLY inadequate for a device aimed at this target. If this is supposed to be "The Treo for Business": FAIL.

THE BAD:
Even with everything other than the phone turned off (Bluetooth, Wi-Fi, push-mail, background programs, etc.) the battery life is disappointing. Without making any calls, if the phone comes off the charger about 9:00 AM, it'll be dead about 7:00 PM or so. If, Heaven-forbid, you turn on any of the features they sell the phone on, it will be dead far sooner.

For someone that's owned a 600, 650, and 700 previously and knows what kind of battery life could be expected from the prior models (yes, don't quibble about PalmOS v WinMo), this is insane.

It's fine to tell the user that an extra battery will handle the problem, but that's not how the product is designed: it does not ship with an extra battery, nor with a charger capable of charging a second battery, meaning you're incurring the additional expense of correcting an enormous design oversight.

I ordered a seemingly problem-solving battery from Seidio-- more than double the capacity with a replacement battery door. Unfortunately, the battery didn't work-- either the battery was bad (Seidio sent me a replacement with the same result), or the Treo just didn't like it. It often wouldn't power up, or the battery would go from showing full to showing empty and the phone would shutdown. Still don't know if this battery may make this phone super-viable.

Also, I've found the call clarity to be awful-- bad even for Treos.

The device has some real quirks: lockups, unexpected shutdowns, more frequently than one could even blame on Windows.

THE GOOD:
The size and weight of the device are great, obviously-- since the battery is tiny.

The display is really clear even in sunlight (much appreciated if you've eyed the HTC Touch Diamond).

The stereo bluetooth works really well-- the first positive Bluetooth experience I've had with a Treo.

The communications stuff (SMS) is still well-handled. The absence of true MMS is pretty easily circumvented with software for WinMo that facilitates PictureMail.

The keyboard is a progressive improvement for Treos-- and this is obviously a strong suit for the Treo. I tried a touchscreen phone very briefly-- my reaction: "Are you !@%!@ing kidding me?!"

OVERALL:
My experience with the battery, the call clarity, and the quirky lockups and shutdowns was enough for me to try another phone (The HTC Touch Diamond) temporarily (more FAIL). I think if the Treo Pro was available on Sprint, I'd be writing a review of that right now.
