I am really surprised that no one mentioned the lack of OneNote, yet. Although it might not actually apply to libreoffice, if their ultimate goal is to replace ms office though then some really really good OneNote alternative has to be developed. OneNote and esp. Excel have to have an extremely good alternative for MS Office to become somewhat less important.
