I use Libre Office as well. It has the same issues that the rest of the big packages have and oodleplexes of features and close to zero integration or at least I haven't found it. The powerpoint equivalent, which is what I use it for, is more ppt friendly than Apple Keynote (or at least the old version I have). I think I see another antique mac in my life sometime soon.
( Aside: One of the reasons for the "rise of the app" is because for the casual user the big suites just have far too many options and nothing intuitive. Most people I know in the IT biz use Notepad, Wordpad or Evernote. Or Notepad++ if it is installed. The Ribbon pretty much killed off casual use of Word. (Far too much stuff changed to be bothered learning it all yet again, at least in the tekkie world).
I got my first mac in the early 90's and had never used one before. It came with a printer and ClarisWorks installed. From opening unpacking the boxes to printing my first doc, having previously only seen machines with dos and wordperfect, didn't not take 10 minutes. Configuring a new printer on a dos machine would have taken me half the day. The next task was to create a little database, write an little mailing and do a mail merge. Job done in about an hour having never seen the software before. /Aside)
