Pocket PC Software - Must Haves

Suggestions

[mipapage]

Okay, we've bought into a couple of new Dell Axims, though my Fiancee and I have about zero PDA experience, we've recently seen friends with them and wonder how we've gone this long without...

So I had a look around [google.com], and not finding anything along these lines (and keeping in mind that URL dropping is anti-tos), can people suggest some must have's?

Along the lines of "it comes with this, but this product is better/cleaner/more features..." etc.
