When collaborating on documents, I typically use Google Docs as over the years editing conflicts have become very rare.
However, for working on collaborateive
.docx files, I'm opting to use SkyDrive since formatting and layouts render more consistently.*
I have a feeling that it's best of all users that are simultaneously editing a file do so in their browser version of SkyDrive.
Or does using the PC version of Word 2010 provide ample conflict resolution and frequent-enough syncing?
* Not Google's fault, the XML markup of Office files can be extremely convoluted.
