DeveloperOne released their Agenda One for Smartphone last week and the Pocket PC version this week. I bought a much earlier version years ago for an early model Pocket PC and liked it quite a bit. But, moving from one device to another as I do, I lost my product registration and didn’t install it on subsequent devices. For the past 8 months or so I’ve been using a Windows Mobile Smartphone (T-Mobile SDA) as my primary device. This is quite a change for me since I usually prefer to use a Pocket PC Phone Edition (the i-Mate K-JAM was my previous phone). I still carry a Pocket PC around with me if I need to take notes since I still can’t enter text quickly enough using T9 on DTMF layout keyboard.

My Smartphone currently only has two add-on applications: Ilium Software’s NewsBreak RSS newsfeed reader and Microsoft’s (now defunct) Pocket Streets (most of my data entry related work takes place on a Pocket PC). So, a lot of consideration goes into deciding whether or not to install and try an application on a Smartphone. The weak calendar viewing capabilities of Windows Mobile’s integrated calendar finally drove me to install Agenda One just to get an informative week-view on my phone.

Agenda One provides alternate views for Contacts, Tasks, and other Calendar views too. But, for me the winning feature is the week-viewing feature. That alone may convince me to keep it on the Smartphone beyond a test period.
