Every day there are fewer reasons to waste money on MS Office. In Panther you can open, edit and save Word files in Text Edit. Mail is now Exchange server compatible. Keynote is a vastly superior product to PowerPoint and you can save in PP format (sure, they still need to work out some kinks, but its 99% there.) Excel is all that's left. Odds are pretty good that the next AppleWorks will fill in all remaining gaps.
Usually I don't like flaming or being uncivil, but do you know what the hell you're talking about? Are you honestly so deluded and hypnotized in your blind hatred of all things Microsoft that you actually, honestly believe that TEXTEDIT can replace WORD? I won't even waste time addressing that. Keynote is a very sweet program, but it honestly lacks the maturity and widespread usage of PowerPoint (and everyone who's used Keynote knows that its PP translation filters are sorely lacking.) iCal is horribly inadequate and slow, making Entourage the only truly viable data management program on the Mac. And yes, there is absolutely no Excel replacement, which is a really big deal.
You're right about one thing, everyday that passes Microsoft loses a little of its edge on the Mac, but it's still a HUGE EDGE. No productivity application available on the Mac has the maturity, compatibility, and richness of Office v.X and, as of now, there is no adequate substitute. Someone will probably respond right back with a list of thirty shareware programs which, combined, perform all the functions of Office, but to believe that the average user will go to those lengths is ridiculous. That being said, there're many things Microsoft could improve which I would pay money for--speed for one big thing, greater reviewing features, and support for more international languages, just to name a few. Those alone justify a new release.
I love my Mac to no end and I'll never switch back to Windows, but this is the one thing that sickens me about the Mac community--its blind hatred toward Microsoft. Sure, we hate Windows, we hate that they stole the idea from us, we hate the ubiquity of that monstrosity they call a GUI, but some people go too far. Get off your high horse and sound rational, for once.
