The folks over at The Apple Blog have an in-depth review of iWork that’s worth checking out. Their overall verdict? They like it!
I’ve tried all of these (and more), and I believe Apple has managed to strike the right balance between functionality and simplicity. Sure, there’s no online document editing, no way of seeing which users are currently viewing a document, no form of versioning or recording changes over time. Currently it’s not possible even to organize your online documents into folders or logical groups (say, organized by Projects or Categories).
But there’s also no need to install browser plug-ins to make it all work. You can share documents with anyone, regardless of their computer platform or OS. One of my favorite features is that I can share with colleagues and know they are not being forced to create accounts in order to use the service — unlike Microsoft’s draconian policy of requiring every Office Live Workspace user to have a Windows Live ID
