I've had this phone (2 - another one for the wife) for a couple of weeks. I rate it superior to the Treo 300/600 and Blueberry 7230 all of which I have owned/used. It has all of the functionality of those devices plus a better camera, better reception due to the quad band feature, ability to play MP3s and a smaller form factor. Battery life is superior to the Treos.The product comes with a battery, AC charger, USB charger/cradle, CD-ROM (for installing software on your PC), and a nearly 300 page manual. The manual is rather daunting until you realize that the contents are duplicated in Spanish. Most users won't bother to even open it up. The device is Bluetooth capable, but a headset is not included with the phone.The internal screen is noticably smaller than that on the Treo/Blackberry devices, however the screen resolution is extremely fine and text can be read about as comfortably on the MPX220 as on the other devices. The screen is much brighter than on the other devices and I had no trouble using it outdoors in sunshine.The Windows 2003 Smartphone software accomplishes its main task - enabling the user to access a MASS of features in an intuitive manner. I'd still rate the Palm OS and Blackberry desktops as slightly easier to use, but then again they have the advantage of needing to accomodate much fewer features. In contrast all three of these devices (Treo/Blackberry/mpx) are much easier to use than standard cell phones.In fact given the low cost of the mpx device (mine was $300 for the pair), I can't see why anyone would get a normal (non-PDA) phone at anything over $100. People who are heavy users of email will still prefer full keyboard phones like the Treo/Blackberry. The mpx does have a text recognition AI system which does an excellent job when typing 90% of a message. However you'll still need to go into multi-tap mode when entering personal names, technical abbreviations, etc. As such, I think the closest comparable device would be the candybar Blackberry 7100t - but that device is more expensive, larger and lacks a camera.I have noted that several reviews claimed the phone's volume output was too low. Either those people have an older version of the firmware (mine was 1.300) or they simply don't know how to use the phone. There are 8 (count 'em) profiles, each with their own range of sound volume and receiver sensitivity. The Normal setting's volume at the highest level is IMO too low. But this is easily solved by using a different profile. For example I use Max level on the Outdoor setting. Treo 300's had the exact same problem, which I solved the exact same way - I used the lowest volume on the Speakerphone setting.Perhaps the advantages of the mpx are best illustrated by what happened to me two days ago. We had to drive to a business meeting about 40 miles away. My companion remarked about how frequently cell phones would be losing reception. On entire drive, my mpx was never less than 3 bars. Multiple times I was requested to place a call on my phone because the other phones would not function. On the return trip back, we popped the top on the convertible we were riding in. I placed a call in a top down convertible at 70 mph and had no difficulty whatsoever in hearing the call. Does that sound like a phone with a volume problem? Moreover because the Outdoor setting not only varies sound output but also reduces the range at which the microphone will take input, my voice output was not scratchy. The person to whom the call was placed later specifically remarked upon how normal the call sounded. Try that on a Treo on the speakerphone setting.Bottom line: If you want a full featured phone but don't need a full keyboard, this is your phone. The dirt cheap price these phones go for compared to similar devices is simply insane.
