As a road-warrior and gadget lover, I've been using so many phone and PDA devices over the years and finally settled on this phone to reduce the number of devices I carry. And I quite like it.Again, as with all my reviews, I've written this for very serious users of devices concerned with usability and productivity because I found very few reviews of the sort so I'm hoping to contribute more to road-warriors out there.Pros:- Still the best pen-based combination of a phone plus PDA currently. It still offers the option to watch movies in high quality and full wide-screen, but the battery life doesn't suck like most Windows based machines.- The PDA features are still more intuitive and usable than any Windows based PDA.- Black Berry push email support now available!- Push and talk support now available!- User updatable firmware (I've done this 5 times now without problems).- Size is still comparable to other pen based PDA phones with keypad.- It has both pen input and keyboard input (albeit keyboard is cramped)- It has the option to remove keyboard (no other PDA phone offers this option, as far as I'm aware).- It's the only smartphone that has a decent keypad for making phone calls.- Great battery life.- Incredible one-handed operation convenience with a 5-way jog-dial. You can truly use most of the features you need most often with one hand.- Flexible OS (Symbian) lets you customize many of the features by mapping them to keys, jog-dials, buttons.- Voice commands that work.- Removable battery.- Ext. antenna option.- Great hand-writing recognition (as far as my experience goes).- Best sound quality (out of the stereo output jack) of any PDA or phone (other Sony PDAs excluded). It sounds even better than my iPods and my Toshiba Gigabeat. Don't believe me? Get some quality ripped mp3s, hook it up to a decent clean amp and output it to home speakers and compare.- Great bluetooth range with wireless headsets.- Great phone reception! I'm still getting decent reception in deadzones where all my other phones has no signal.- Call sound quality is superb.- Speaker phone works very well and it's activated quickly during a call by simply flipping the keypad open.- Awesome sounding ext speaker, too bad only mono, but then on such a small device there isn't enough spatial separation for 2 speakers to produce true 3D sound anyway.- Comes with very decent software bundle to edit Word docs, Excel sheets, view PDF, music, video player, WorldMate Pro, Handy Date are thrown in for free as well.- Very complete out of the box experience: good amount of internal RAM for productivity, S/E has thrown in a decent amount of very popular software, decent (certainly not great) carrying case, USB sync dock, stereo headset/hands free, syncs great with Outlook, Notes out of the box.Cons:- At full price, I'd expect WiFi, but at time of writing, you'd be silly paying more than $450 for a new P910 series.- Cramped keyboard, I mean really cramped. But personally I don't have any problems with it, albeit I do have flexible, precise musician fingers.- VGA only cam, but whatever, I certainly hope no one is so easily pleased that they'd be impressed by photo quality from any phone on the market.- MS Duo expensive, but this should only impact those who insists on watching all their videos on their phones, I personally found its internal memory more than enough for a PDA.- Should've taken out the camera and made the device smaller.- Slower processor. When the phone switches from one app to another, it definitely delays for a second or two. But then that's why the battery life is so great, your pick.- Symbian UIQ PDA feature doesn't quite match up to that of the Palm OS (no Palm's fast global search, customizable hand writing short-cuts like copy and paste). I'm a road warrior and I use a lot of short cuts to save time and by far. Palm is the most usable PDA OS for productivity, followed by Symbian. Most road warriors in my office consider Windows based PDA toys and I agree. But then even Palm no longer makes a pen based PDA phone to take advantage of key stroke shortcuts, so this con point is moot.- Does not come with travel sync cable, you'll have to take the dock with you or buy an aftermarket cable. This is ridiculous, they should've made a USB cable that can plug into their dock so you can still leave the dock at home while on the road.- When paired with Moto's popular bluetooth wireless headsets, the voice quality for both the speaker and the listener isn't as good as when Moto's headsets are paired with Moto phones.- Bluetooth connection to wireless headsets are prone to static a lot more than Moto phones.- Built in speaker phone can be louder. I doubt it'll be usable in loud environments.- While the audio output jack is stereo and is a standard, universal micro-jack, it would have been better if the jack were a standard mini jack so I can use any of my headphones without having to use an adapter (sold separately).Conclusion: Overall, for a PDA and phone, the P910 is still the best of both worlds at time of writing. I didn't wait till the next update of the phone to buy because the next phone will have a stupid built in keyboard that cuts away half the screen and most likely the pen based option will not be available on the next P-series. That's too bad because the pen is still the best when it comes to fast input. Without the pen, I'd have to waste time scrolling through different fields just to enter data into the one field I wanted to get to. Plus, I like to see anyone input Chinese characters with an English keyboard (yes, I know I can use Pin-Yin, but then I'm a road warrior, PinYin is simply too slow. With a pen, I simply write). So if you like pen based PDA phone with a keyboard and decent keypad for dialling, get one of these puppies before they're gone. Have fun shopping!
