My workplace wanted me to get a cell phone so that they could contact me when in transit between meetings. I had been fascinated by the idea of Blackberrys and Treos for quite awhile. One of my coworkers was upgrading to a Blackberry and was willing to let me use his Treo 650.I learned about Palm by using a Zire 72s (see my review). The Treo's applications were just enough different that it took me a few weeks to feel comfortable with it. However, I have come to enjoy the Treo and really like the capabilities.The real power of the Treo is that it allows you to combine your PDA and cell phone into one combined package. If you don't mind lugging around multiple gadgets, then the Treo may not appeal much to you.In no particular order, some of the issues that I have had are:* The price is just too high. If my work place hadn't "lent" me one, I never would have paid this much for a cell phone/PDA combo. The Treo must get its base price below $300 before I would consider buying one with my own money. Indeed, if the prices don't go down (or my workplace won't sell me the current phone at a discount when I leave); I will probably buy something like a TX and try to make "Skype" VOIP calls!* You really need to buy a screen protector especially if you have oily skin or wear lots of make-up.* As another reviewer has noted, the "Dint" sound every time there is a change in network status is really annoying. If you turn the sound off, then the vibrating mode is too weak for you feel it if the phone is in a coat pocket.* The amount of memory with this phone is a joke. You really need an SD card. The bigger the better. I plan on buying a 2 GHz SD card. I would buy a 4 GHz card if they made them yet. While this could have been alleviated if Palm had added a life drive, it may be that SD technology is growing at a faster rate than one would care to replace hard drives.* Data is just too pricey for now. Moreover, the times that I've played around with it, it is very slow like a 28.8 (or less) modem. On Palm's web page, you can buy a WiFi "Sled" - whatever that is - for between $129 - $149 dollars depending on sales and rebates. I'm not sure yet, but that might be something worth pursuing if you like data connectivity but don't want to use the pricey cell phone data plans.* There has been a lot of discussion about 2.5MM port for the headset. Apparently, 2.5MM is the standard for cell phones while 3.5MM is the standard for virtually every other portable device. In my case, this is not an issue. I'm not an "audiophile" so I simply use my cell phone ear piece to listen to MP3's. If that is an issue for you, you may consider getting a 2.5MM to 3.5MM conversion jack - they are sold at most Radio Shacks.Having used a Zire 72S and now a Treo 650, I find that I'm developing an opinion on what the ideal personal electronic device might look like in terms of capability. My completely subjective opinion of what the ideal personal electronic device would look like and some comments about how that compares to the Treo 650 are:* Ability to download and read books on-line: The Treo provides this via adobe acrobat reader. I find that I'm able to read a lot of material while riding the bus/subway or during other odd times just by keeping research materials on the Treo.* Ability to connect with printers, PDAs, cellphones, and computers wirelessly.o WiFi: Lack of WiFi is a real weakness of the Treo. I don't want to be locked into paying for an overpriced data network via the cell company. Even if I was willing to spend that much money for convenience sake, as a consumer, I should be able to switch to the faster WiFi networks when I happen to be in a hotspot.o Blue tooth: The Treo has this. I use this mostly to send files to between my Zire 72S. However, it is clear that if you give a little thought, one could cheaply use Bluetooth to build a wireless network in the home to tie cell phone, printer, and computer all into one tool. Moreover, some of the cars these days are coming out with blue tooth navigation systems that make this an intriguing option.o VOIP: Currently VOIP is growing in popularity because it is cheap. Again, as a consumer, I would like to be able to use WiFi hotspots to make free phone calls when possible. It may be possible to do this now with the right software, but I don't know how.* Personal scheduling information that can be shared with Outlook and other PIM programs: Palm has this down cold, the Treo is no exception.* Camera and Video Camera capability with a reasonable resolution. Treo has a 1 Mega pixel resolution camera. No flash. It is an interesting toy. I use it to take pictures of my luggage when I fly - "It looks like this, see." To take pictures of where I park and anytime I want to take an impromptu picture of something.* Contact information that can be shared with Outlook and other PIM programs. Again, Palm, including the Treo, has this down cold.* Ability to create, edit, modify, and view MS Word, Excel, and Powerpoint files. Documents to go on the Treo does this. If you are upgrading from older versions of Documents to go, you might accidently corrupt the files. This results in documents to go restarting your Treo every time you try to open a file.* Ability to synchronize all data files with work and home computers. The Treo does this well. However, I'm considering the efficacy of an external SD card reader for home or for work. Just seems that it takes most of the time hot synching to move adobe and word files.* Cell Phone: This is the real plus of having the Treo.* Ability to download audio and video clips and then listen/watch while on the go. I have yet to get a video file to work on the version of Realplayer on the Treo. Not sure what I'm doing wrong. I will continue to try and see what happens. There is some decent freeware for the videos and some third-party software, but will try that at some later point. In terms of audio files, I use itunes to download CSPAN, NPR, and PBS shows that I like. Once they are on the desktop, I use Realplayer to move the files to the Treo's SD card. Note: This is not intuitive, but strangely enough there are directions if you hit the help button on Realplayer on the Treo.* Capability to make long (eight hours or more) of digital voice recordings for seminars meetings or just to capture your bosses latest guidance on a project. This really bothers me. If the Treo could do this, I would be down to one and only one electronic device.Bottom line: I really like the Treo. I have learned how to do most, but not all the things that I need it to do. However, until it gets below $300, I do not think it is a good buy.
