Softalks update of their "Spreadsheet" application has just been released at the App store.. I got my 'download' notice yesterday. I can import or export my spreadsheets from my iPod Touch via Wifi. You can also use e-mail. I set up the Wifi in about 15 seconds. Fast and simple. Right now, the file format is XML format (filename.xml) so you need to open it in Excel on a PC or Mac. A "Numbers" version should be in development soon (I hope). Otherwise this is a great app, uses all the standard formulas, etc.
