The title pretty much says it all. Why does my iPod Touch open an .xls windows created excel spreadsheet, but my iMac doesn't? I am downloading Open Office now, but I'm just trying to understand why it works on the iPod, but not the iMac?
The iPod comes with the software to read Word and Excel docs by default. You can't create or edit them but you can read them. If you want to read them on a Mac you have to add MS Office or an equivalent. Pretty simple actually.
