Some reality would be nice...
I know, add text and RTF view/edit to... Pages. Give the PDF manipulating capabilities that Preview has to Pages as well. Then set it up so that whenever I save text or PDF's to iCloud, Pages will let me do viewing/editing. I don't mind iBooks displaying PDF's. It works for me when I'm teaching (our instructor manuals are all PDF's). When someone sends me a PDF to fill out, I'd like to have one editor to worry about using.
This just seems to be common sense to me. Why are we fragmenting into multiple apps and viewing/editing? Why make a mess? I thought the goal of Apple was, "It just works." How does what I recommend NOT just work?
For that matter add MarkDown to Pages, with a viewer and an export. Then it would REALLY be 2014.
