The Google Docs people have released another great feature, the ability to edit spreadsheets on the T-Mobile G1, the iPhone and iPod touch, and the Nokia S60. To give it a try, go to m.google.com/docs. This is a fantastic feature and will make mobile computing even better. I am still amazed that we can view cloud based spreadsheets/docs on cellphones, and now with the ability to edit them, it is mind blowing.
Update: Google has also added more features to spreadsheets. Data validation has been added, which allows control over what collaborators can enter into a spreadsheet. Forum summarys can now be viewed for a spreadsheet, and the size limit of spreadsheets has been increased.
