I just love EditGrid, not only because it is the best online spreadsheet I ever used, but it is always giving me something which the Chinese web companies dont really care about but the global industry is fancy of. EditGrid has multi-languages version; it has a nice widgets running in Netvibes and Pageflakes; and tomorrow at Office 2.0 conference, its iPhone version will be rolled out. If you dont have a iPhone in hand (like me), you can still experience it on a normal web browser or a iPhone simulator such as iPhoney at the url: iPhone.EditGrid.com.
EditGrid enables the spreadsheet in your pocket, and it definitely has my credit. But to be fair, it is not the first one announcing the pocket office. Zoho has released its office suite called iZoho including its Writer, Sheet and Show back to late June.
