So … for those who don’t know, I’ll describe the features of the PDA (Personal Digital Assistant) that I use, a Treo 650 (including some optional features):
I track all the contact information for my business and personal contacts: For each person or company I can store six phone numbers, two email addresses, two mailing addresses, two websites, birthday, anniversary, a photo, and unlimited notes. I have about 400 entries. I track all my appointments and tasks, including repeating tasks.
All this info is password-protected and encrypted on the device so that if I lose it, they cannot access sensitive. (For the techies, the encryption that I use is Blowfish-128.) Also, each day the entire contents are backed up to an encrypted memory card that holds more information than a CD.
It synchronizes with MS Outlook, which means that I always have another copy of my data in case I lose my PDA, it crashes, or I buy a new one. (Also, I regularly backup my hard drive to DVD.)
The device is also a cell phone, with four bands, meaning that I can use it anywhere in the world that has cellular service. The unit has a speakerphone for handsfree operation and a Wireless headset. Also, the phone will communicate (without wires) with car so that, as soon as I enter my car, I have handsfree operation through my car’s stereo system and microphone.
It also has:
A backlit keyboard and a stylus for input and editing.
A built-in MP3 player with room for 100 songs on the memory card.
A digital camera (with video and audio)
Digital albums
Email (I can access my personal and business email accounts from anywhere there is cellular service.)
