What software should I buy for my pocket PC?

What are the must have applications for my Pocket PC? Are there any wordprocessors, spread sheets, personal finance, PIM or other utility programs that I should get? Or should I just stick with the default programs in the machine?

Remote controller for pocket pc. It is great for messing with my neghbour’s tv!

Go to the microsoft site and get Pocket Streets and download some of the city maps they have, even better, get a copy of Streets and Trips, which gives you the ability to create your own maps.
