Try here - a sampling:
A bunch O' spreadsheets, etcAlso
My PPC version of an EC120 W&B program is up there. You can run Excel spreadsheets on a Pocket PC using a progam called SpreadCE - it works much better than Pocket Excel.
Note: if you run my PPC program in Pocket Excel, it will disable the graphing function (which will then not work in SpresdCE).
BTW, I use a Dell X50v with a 1GB SD card and a rhino•skin case - works great!
