Welcome back to the Smartphone Round Robin! Dieter has made it through round 3 of the Smartphone Round Robin and got to use his main brain this time around. He's finished with the Treo Pro and has posted his full review.

Dieter explains exactly what a "Treo" is and what distinguishes it from other smartphones. He talks about the Treo having one step access, giving us the ability to do many things with one hardware button, and with no configuration whatsoever.

Dieter also talks about the legacy of Windows Mobile Treos and how the Palm Treo Pro fits in.Head over to WMExperts and read Dieter's full review. It's a great read and I'm sure you'll learn something.
