what i see of apple software in my short experience is that they tend to try to integrate apps together and into the OS.
why wouldn't they at least make a light word and spreadsheet program that comes with ilife that works like itunes, iphoto, etc. one that not so much competes with ms office, but uses the same standard document types and puts an apple twist on it.
integrate a diary and/or blog feature into the 'word' program. integrate the spreadsheet program into other apps so you can easily port raw data (system resources, itunes play counts, etc) into easy to read spreadsheets or graphs - sort of how sharepoint does, if you're at all familiar with that.
of course the layout and tools would have to be uniquely mac, but keep formatting completelyin tune with office.
why not?
