Save for rare cases, I'm really content with the Apple apps: Pages, Numbers, Keynote. And I love the Apple document management. Document always saved and versioned.
If I had to go back to Linux, and if it were an option (which it’s not), I’d pay $300 without hesitation, to have all Apple’s office-like and other “bonus” apps on it. They’re my top choice in practically every category, when outside factors aren’t deciding for me (it’s usually MS or Google crap, when that happens—man, I hate Google Docs)
