View/Edit Microsoft Office documents

Hi all,

What do you use to view and edit Microsoft Office documents on your iPads? I assume Pages can deal with Word docs, but what about Powerpoint, Excel, and Publisher files? Do you all use Google Docs, Microsoft Office Online, Zoho, or some other service?

My 3 requirements for the iPad are:
Insane battery life
Ability to view/edit PDFs greater than 500 pages (iAnnotate)
Ability to view/edit Microsoft Office documents

2 out of those 3 are already sorted. Thanks.
