I don't work for Softshare (they're in the U.K.) but have to say they have the best spreadsheet out there for the iPod/iPhone. Of course they are the only one I know of! Took a bit to get used to it, (instructions are in your intuition folder) but it works fine. They promised to add some enhancements in the next revision, so that you can import and export an Excel compatible file. I'm guessing Numbers (iWork) files will be able to work as well. Hope so. Maybe this app isn't a must for everyone, but for keeping budget and expenses, it does the job and I can wait a bit longer for the upgrades. I tried AirSharing for spreasheets, but can't get it to display larger than 'thumbnail' size, after following directions on how to do it. It was free, so can't complain I guess, but Spreadsheet (catchy name, right?) is a winner.
