It's not that Apple's iWork is much beloved, but at just $60 for all three applications--compared to $125 for a home and student license of Office--Mac users can put up with it. Apple clearly doesn't place a huge amount of importance on its productivity suite: The last major revision to the bundle was iWork '09--as in the year 2009. My handy $20 spreadsheet program informs me that that's four years ago. After updating the software fairly frequently early in its life, Apple has left the programs to languish. And I don't blame the company a bit.
I'm not claiming that office applications are going to die out--that would be a stupid argument to make. But I do find them to be an anachronism. Mobile platforms and the Web have taught us the flip side of that old saw: If you hate something, let it go. If it doesn't come back, good riddance.
