They could spend some time on making Numbers and Pages as functional as Excel and Word.
Well,
that would be a spectacular waste of money!
Pages and Numbers look great to me - they're pretty capable, do a pretty good job of importing/exporting .docx/.xlsx and it's good that Macs and iPads come with half-decent wordprocessing and spreadsheet tools. If you want something for purely personal use, or live in a little Apple-only bubble, that's fine.
However, I never use them for work because
that requires continually bouncing files back and forth with people who use MS Word & Excel on PC
and Mac - and however good Pages & Numbers are at importing/exporting .docx/.xlsx files it's
never perfect and I just don't need one more thing that can go wrong.
Apple could make Pages the most brilliant and powerful word-processor
ever and nobody would look twice at it before reaching for MS Office or Google Docs because - like it or not - MS and Google own the office app market, work on PC, Mac and more and having everybody on the project using substantially the same software just makes sense.
If I want an online/collaborative document I'll use Google Docs because that's what everybody else is most likely to be familiar with and it's "free". If I really want to poke MS/Google in the eye I'll use Libreoffice because anybody can download it and it runs on anything. What I'm
not going to choose is something that only Apple users can access and which exported files that I'd
still need to check in MS Office before distributing to less tech-savvy people.
Like it or not, MS and Google have the office software market sewn up.
