Or you can go to
Softmaker and check out their two main products,
Planmaker and
Textmaker, both excellent replacements for the built in PocketExcel and PocketWord. They are full featured spreadsheet and word processor applications, and IMHO are what MS should have put in Windows Mobile in the first place, but that's another argument
I use Textmaker all the time, both on my X50v and on the desktop.
