My trusted Treo 650 was beginning to show signs of wear recently, and after some long service, I decided to put it out to pasture and upgrade. I had my sights on the 755p, but that was a bit out of my price range, so I went with the 700p. On the surface, the phones are virtually identical in overall shape (other than a few cosmetic differences in shape) and weight. Basically they *feel* about the same.Personally I like the silver finish more than the 650's blue-ish tint. The buttons seem more sturdy and there was an overall more assurance that the buttons had been pressed when using the thumb-key's. The newer shape to the keys seems like almost an afterthought as far as an upgrade goes, but I ASSURE you this change is definitely better than the old teardrop shapes of the 650. I like typing even more on the 700p.There are a couple of serious flaws in the way the new key pad is designed. I imagine that Palm was going after the fans of the 600 & 650 design when they upgraded to this model, so changing the dedicated Send & Off buttons simply made no sense at all. The Green Send button is just that: a Send button and NOTHING else. This DOES take some time to get used to if you are familiar with the 650. It has taken a lot more time to get used to than I would like to admit, and that is in part due to my stubborness in accepting that the designers in their attempt to Upgrade an already stellar performing smartphone, they literally took a step backwards here. The same goes with the Menu button which on the 650 USED to be huddled next to the Red Stop/End button, but now has been banished to the bottom-right corner next to the Alt and Space bar. I seriously want to know what was up with that decision?? Pure & simple it's nothing more than a design FLAW if you ask me. A button such as Menu which is used so frequently to be moved to such an inconvenient location borders on downright stupidity. However it isn't an insurmountable situation. Slowly but surely I am getting used to it--although totally against my will.I LOVE the 5-Way Navigation button's new rectangular design! Finally something to be happy about. The entire button layout seems more stable than before and after pressing the button, I can't say for certain, but it seems there is a more obvious *click* feel to it that the 650 lacked, making this a giant leap ahead in my opinion.Receiving calls is much the same as before as Palm simply refuses to do almost ANY upgrades in the Operating System for fear the learning curve may be too much for us (sounds as good as any other reason I've heard...).I DO like the new *Ignore With Text* feature that comes along with each incoming call allowing you the option to at least let the caller know you recognize that they called you but you cannot answer right away. Cool nifty feature for sure. Hearing calls is a definite plus over the 650, too. One major lacking problem the 650's had was poor volume during a call, and I am happy to say Palm seems to have made up for that here. Otherwise the call features seem to be (for the most part) almost entirely unchanged (as far as I can tell).The usual PIM features seem to be (again, for the most part) pretty much identical to the 650's. It would have been nice for Palm to have at the very least offered some new color schemes to dress up a system that has remained virtually unchanged for what seems like forever now...but Palm didn't see it that way, and while that makes getting used to a new phone one less thing to have to learn, it would have been nice to have even so.Maybe I'm an idiot, but I haven't figured out how to snap a photo and send it using the phone features rather than Bluetooth or email. I DID discover that GMail offers FREE POP email service, which is a cool feature which allows me to send photos, video and documents as attachments. You can even set the phone to check your email account as often as every 8 minutes or so, even which days of the week to perform that task and for which hours during the day to do it. Nice touch. However yet another major FLAW comes in the Web browsing section. On the 650 when you were finished surfing the 'net or checking your web-based email you hit the Menu Button and scrolled down to the bottom and hit Disconnect...but for some unknown reason the disconnect button is not there. In fact for several days the only way I was able to discover how to disconnect from the internet was to simply power my phone function all the way off (something that takes almost 3 times longer than it did on my 650), otherwise you are still connected whether you like it or not. I had to Google a remedy, and while it's a small pain in the arse, it does work (you go into Prefs, click on Network, and at the bottom-right is a button that will either say Disconnect or Connect depending on your status). Why make us jump through additional hoops when the original design was just fine? I wish I knew.Supposedly the 700p comes with faster EVDO download speeds which at peak times is rumored to be around DSL speeds. I am not experiencing this. That could be for one of several reasons: 1. we simply do not have that service in this area yet (I suspect this is the case) or 2...well, lets say that I don't think we have EVDO available just yet. I will admit that I believe the 700p IS faster downloading than the 650, but at best it's only faster by about 20% I'd say. Barely noticeable actually. I also have noticed a lag time when downloading pic's off of websites that you cannot move the screen around to look at the pic until AFTER it has totally finished loading, when the 650 allowed this feature. Minor gripe I know, but I thought I'd say it anyway. When going To and From websites, it's nice when using the Back feature that it doesn't have to take the time to entirely RE-LOAD the whole page if it had already been loaded previously. Really nice and much quicker, too.Battery life seems to be around 10-15% less than what my old 650 battery was giving me after 3 years of solid usage. Go figure. I hear the 680 is embarassingly bad in this area. Word has it the 755p is back up to about what the old 650 used to be--which is kinda embarassing right there if you ask me.Camera is MUCH better than the 650...but 1.3mp?? Is that all we could get these days when even the cheap phones can almost all outclass a Smartphone...?The added memory is not only welcomed but was the absolute biggest flaw of the 650. It practically forced you to buy an expansion card right up front. I found my memory was full on the 650 by the end of the day I took it home. While 120mb is a nice upgrade, I have to wonder why they stopped there and didn't give us at least 512? It doesn't take long to fill up with the amount of stuff that is available these days, so I gotta wonder about that.I read about pairing problems between the 700p and Bluetooth headsets and sure 'nuff mine was problematic, too. Although upon further inspection it turned out I had a bad headset which I am getting replaced soon. We'll see if that so-called problem continues with a good working model.Overall I am about 80% happy with the upgrade. What the phone seriously needs in order to REALLY compete with the Blackberry's, Moto-Q's and Blackjacks out there is pretty simple, really:#1. More memory. It ISN'T asking that much to have standard 1 gig, is it?#2. A Palm OS overhaul. Keep what works, but give it some flashy new graphics, colors, let your imagination run wild. There doesn't have to be a gigantic learning curve in order to make it the next big thing that all Palm OS fans will want to upgrade for.#3. A return to the basic easy functionality that was almost perfected in older models (ie put the menu button back where it belongs!).#4. A better digital camera and a flash if at all possible. Some really basic phones today come with 2-3mp camera's and we are still stuck in 1997 with 1.3mp. Kinda embarassing really. Oh, and throw us a few tricks to improve picture quality after the photo is taken, too.#5. Make the whole thing slimmer. NOT more narrow (like the almost too small Centro) just thinner. Actually I'd settle on a wider model if it were thinner.Am I asking for too much? Based on some of the phones available today at similar or even lower cost...? I'd have to say no. It remains to be seen if Palm actually wants to seriously please their customer base. They did for a while, but boy has that gone downhill the last 7 years or so. While I am still a big supporter of the Palm based OS, I can see the writing on the wall for its future if those responsible fail to recognize that many other manufacturers are kickin' their behinds in almost all ways...I'd LOVE to be proven wrong here, but who knows? Time will tell.Hope my review helps.
