bane? Yes. Apparently it is a better, more stable, smaller file... but good grief.
Get this: A .docx file saved with Microsoft Office '07 will NOT open in Mac Office '08.
I can't think of anything more frustrating when it comes to collecting papers from my students.
(I know--.doc will work pretty much universally, but why have .docx on both versions of the software if it doesn't work universally? Apparently, there will be some sort of conversion available later, but in the meantime-- all I can say is blec.)
