Editing GoogleDocs on iPhone & iPad

I found a 3rd party solution for editing GoogleDocs with both my iPhone and my iPad. There are apps available that make this possible: Office2 (squared) for the iPhone ($5.99 in the iTunes App store) and Office2 Pro for the iPad ($7.99 in the iPad App store). There is a free version for the iPhone/iPod Touch, but it doesn't allow saving. The Doc2 app is $3.99 (saves documents); same price for the Sheet2 app (saves spreadsheets). 

I was able to open GoogleDocs Document and Spreadsheet files, edit them, and save them to the web. All changes were made to GoogleDocs. I also created documents on my iPad and iPhone, and was able to copy and paste text between those documents and my GoogleDocs, so I am able to work off-line. I can also open files stored in Box.net, Mobile Me (iDisk), and myDisk.se.

I bought the Bluetooth keyboard and the VGA cable. I also downloaded Keynote for the iPad, and my daughter has challenged me to do my next presentation with my iPad. I have three weeks to prepare! It looks like I can't plug the iPad into power while using the VGA cable. But I am getting more than 10 hours on the battery! Just need to start with a fully charged iPad.
Next I will explore online storage from the iPad/iPhone!
