When using Windows there is Open Office (Free), Chrome has Docs (free), But Apple charges $10 for each app (Numbers; Pages; Keynote; etc.) used on an iPad. Why does Sun and Google offer their Office products for free while Apple charges for weaker apps? My new Retina iPad is on a FEDEX airplane somewhere over the Pacific Ocean as I write this, so my question is: Can I open Chrome on my iPad and run "Docs" which offers a very nice spreadsheet application, on my iPad or do I need to spend $10 on the Apple Numbers App. which doesn't appear to have as many features? I am able to access Chrome Docs on my iMac and it syncs the files with my Windows notebook. I would like to have access to the same files on my iPad. Can this be done?
