Can anyone summarize the pros and cons of each as a desktop GTD tool?

I use a Palm, and have happily used the Palm Desktop for my GTD system for the past 18-24 months. I just took a new position in a more techno-oriented company, and while I can certainly still function w/ Palm Desktop, there may be some gains if I switch to Outlook as my GTD tool of choice. I'd probably look at setting up Outlook per the GTD whitepaper.

I'd appreciate any thoughts, and thanks in advance!
