I was using open Office saved it as word as some recruiters requested it, yes PDF wasn't acceptable to them despite it being my format of choice to keep formatting. Noticed between OpenOffice and word versions, word viewers etc formatting was inconsistent. Sometimes what fitted onto a page here and there spread just onto a second page making the resume longer than it should be wasting space, and other elements shifting. I even used a trial version of office 2007 and found inconsistencies between my documents and other office versions. I do wish they would all accept PDF, it wasn't as if my PDF documents were not search-able, printable etc.
