Re: "run MS Office"
And LibreOfficedoesn't have an Outlook equivalent that handles email and calendar across all my devices.
Or a Notes equivalent, like Onenote ( or Evernote, sadly now reduced to 2 devices for the free version, no good to me). Sometimes its formatting can be quite quirky still, especially in tables.
It use it for most of my everday stuff - but have to keep Office 2010 as well. ;-(
