I just returned from a short business trip to New Orleans and while traveling in the airport and on the airplanes I saw many mobile devices. The funny thing is that something like 95% of the devices I saw and heard (that default ring is distinctive) were Treo devices. I personally had a Treo 650 for well over a year and loved most everything about the device, except for the phone quality. Seeing all these Treo devices set off the new device urge again and got me to thinking about a Treo 700p with the fast Sprint EVDO service. I use T-Mobile, but adding the Sprint EVDO service isn't that costly and the ability to get such fast wireless service has me seriously thinking about the move. I don't know when T-Mobile will ever get their HSDPA or UMTS service up and running and all the talk of high speed EVDO access has me itching to get connected.
It seems that most of the traveler's I saw using Treos were using Treo 650 devices so I think there is definitely still a market for Palm OS devices. I also believe these same type of buyers may enjoy using a device like the Nokia E61 that offers a similar user interface (and isn't sold with a Microsoft operating system), but supports higher functions like true multitasking, quick application switching, integrated WiFi and more. Nokia and the Series 60/Symbian OS need to do a better job of getting devices into the U.S. and marketing these devices to compete with the BlackBerry and Treo business user before I see Nokia E61 type devices on the road. My move from the Treo 650 to the Nokia E61 was based on the fact that I added integrated WiFi, much better stability, and better phone functionality with the E61.
