Just curious, but why is it a shame? It's not a contest. Should apple rush it just to be first? If they did, you would be bashing apple for rushing and making mistakes. Apple just can't win with this crowd. I'm so happy that Apple succeeds very well despite the bashing here. Obviously, the bashing isn't very effective.
I don't think it is a race so much as it should be a given that Apple's first-party software supports all of the features that it builds into its operating system on day one. Can you imagine how much ridicule there would be from the Apple camp if MS Office lacked features in the new Windows 10? People would say "typical MS and their low quality, this is why we buy from Apple, products that just work" and "we buy Apple because the hardware, software, operating system are all integrated and therefore better."
Now, I am not actually complaining about this... I am just telling you the reasoning behind it, which I do agree with. Nevertheless, I don't use iWorks, so I don't have a strong opinion about this per se, but I am only speaking in generalities.
Now, as for the other people who are saying that iWork is just as good or better than MS Office. That may be true at this particular moment because Office is buggy and keeps crashing. It may even be true across the Mac platform (I don't know, I don't use iWork, like I said)...
But functionality, unfortunately, isn't the only point to a Word processor. If it were, everyone would use Scrivener, Mellel, or Nisus Writer Pro, and certainly not iWork or Office. For Excel, I really don't know of much else that is better. But as far as word processors and presentation software, compatibility is KEY.
I am honestly sick of Apple fans acting like compatibility doesn't matter, and then later hearing the same people pray for the day that PC games are compatible with Macs. People don't JUST use Word and PowerPoint because they are good (which, they are *good*, though perhaps not always great). They use them because they are the standard, for better or for worse.
Rarely has anybody contended that Word is the best. Because it quite clearly is not, even though it is *basically* adequate. The point is, it is standard. If no one is ever going to read your documents, fine, use whatever word processor you want. But, if you are like most people, your documents are made to be read electronically by people in a multitude of locations. For this, you pretty much need Word.
I use other Word processors, but before I send my document anywhere, I open it in Word, double check its formatting, and then save it as a Word document. For compatibility purposes, Word is great because it IS compatible.
