Personally, I think Apple should forget about what microsoft thinks. They already have most of an office suite in the form of
iWork (maybe an entire office suite if the
Numbers rumor is true), which is already pretty good
and currently supports, microsoft formats, PDF, flash, Photoshop, XML, etc.
Another cool thing, but definitely will not happen, would be if they actively supported OpenOffice. I know there is already
NeoOffice, but it would be much better and slicker with Apple's help.
Who needs Microsoft anyway?
