I've been lurking on this site for a while and I have learned a great deal.

We are an enterprise customer of Verizon and we were given a few Samsung PDA's including server software to test their verison of Blackberry.

We provide a cell phone and a Blackberry, using Mobiltex, for those who need them.

The Verizon version of Blackberry uses GPRS. I tested it thoughout the Bay Area and it was markedly inferior to Mobiltex. The push feature was hit or miss. For example, I couldn't get a reliable signal at home. The Mobiltex is rock solid all over the US.

The Samsung device worked fine as a phone and allowed much easier on the road sync with Outlook when I could get a connection. But the phone was just not as comfortable as a simple cell phone. And the lack of a keyboard made the Samsung impractical for sending email.

We passed on the device. The changeover would have been quite costly. We look forward to the day when we can provide a single device for all our wireless needs, but at least Verizon's GPRS system, at the moment isn't it.
