My mother is not anti-Apple. She owns a Mac and an older iPad, but has always been perfectly satisfied with her trusty copy of Microsoft Word. “That’s what everyone uses,” she says.
I use iWork as my go to office suite, not out of spite for Microsoft’s suite, but because I try to keep my Mac lean and mean. So I install one app for each purpose and since Keynote is my favourite presentation tool, using Pages was an automatic choice.
