I owned a Treo 180, but after many years of service and a lot of duct tapings, solderings and super-gluings, the Treo 180 was due for retirement. I'd been planning on replacing it for a while, but since Palm seems to crank out a new smartphone every three seconds, I was having trouble deciding on which model to buy. I wanted to get a 700p but since there were no CDMA networks available in my country, I settled on a 650. The Treo series of PDA phones are no joke, they have always been top-of-the-line products. The 650 is no exception. It's an excellent PDA and an excellent phone with few flaws.Since I could write a book on why this product is so great, I'll just list its few flaws:- The headset port is on the bottom of the PDA...the worst place for it to be.- Instead of a dedicated power button, the 4th hard button is now the power button. WHY!?!?!- Palm has been promising WiFi drivers for this PDA since it's launch, none have been delivered so far. Don't tell me about the finnicky, overpriced Enfora WiFi sled...- The Media program's viewing abilities are very basic. Three levels of zoom, pics come out looking badly pixelated when resized, videos taken in low-res mode are shown in a TINY box. A different photo viewing app might be a better choice. TCPMP is a better app for video playback.- The button layout sucks for gaming. You'll end up accidentally hitting the Home and Menu keys often.- More built-in memory would be nice. It's not bad now, the NVRAM system gives you 22MB of user-accessible memory, and the Treo has 10MB of dedicated RAM where programs are loaded to and run. And this PDA is QUICK. I'm a very impatient person, and I've never been irritated by having to wait for something on this PDA yet.- The screen and keyboard backlights cannot be independently controlled without extra software (such as keyshades or KBlightsoff). The keyboard backlight is rarely needed, it would seem to be only common sense to include such an option. When switched off it saves a HUGE amount of power.- The camera's picture quality isn't great, but it's on par with most high-end cell phones. BTW, the Sephia effect is great for taking pictures in the dark.- The LED is pointed directly into the user's left retina like a frickin' laser beam. There is freeware available to turn it off if the irritation is too great.- Doesn't come with a spare stylus. Every device that uses a stylus should come with a spare stylus. No matter how careful you are, it could slip out of your fingers and into a storm drain.- In a few instances some functionality (mostly keyboard shortcuts) has been sacrificed for user-friendliness. An annoyance to power users like me.- The biggest annoyance...on the Treo 180, if you held one key on the keyboard and pressed another, the characters would come out in sequence. This allowed the user to type more quickly by rolling the thumb from one key to another. Try this on the 650 and only the first character comes out. This makes the keyboard a bit more user-friendly to newbies but it can hamper the typing speed of thumb keyboard veterans such as myself. Not a big issue, just an annoying limitation.Well there you have it, a full list of what's wrong with the Treo 650, an otherwise outstanding device. IMO, all those problems put together don't justify giving this product less than five stars. I have no reliability problems (I have the latest firmware) and like I said, it's QUICK. Dissing this device is like dissing a supercar because it's hard to get into and the boot is too small, and I would recommend the same solution - look at an entirely different product. So, if you want a simple, fashionable phone just for everyday communication, move along smartly. If you want a no-nonsense feature-packed lightning-fast PDA phone, make sure you consider a Treo.I highly recommend the following accessories: JAVOscreen Treo 650 screen protector, Sandisk Ultra 2 SD-USB card, 2.5mm-3.5mm Headphone Adapter.
