In response to Digdah...
I have personally used and tested the Samsung SPH-i700. I found this phone to be the closest thing that a corporate user will need, if using Verizon Wireless as the carrier, but still has some "family-oriented" features.
I prefer PalmONE devices for stability, but this Samsung uses Windows powered PocketPC. Some corporate users like Windows powered phones because they can store and sync documents from work to home and vice-versa.

I do like this phone, but was overkill for what I needed. A lot of executives use it though.
