Will there ever be a day that Apple releases something that doesn't need to be..

I'm not sure what you're implying with this question. None of the people I know who own Apple products have a "hacked" (i.e. jailbroken) version except for those who needed the phone unlocked for a different provider.

Apple formula is based in closed formats, closed system, closed software. I don't think they ever have something open.

hard to change if it's working don't fix it

The answer depends on the user. Most people that purchase Apple products are happy to buy something that they dont need to worry about 'going wrong'. Apple ensure this by keeping their hardware and software 'closed'. If, on the otherhand, the user wants more than Apple 'allow', then hacking is the only way to go.

I cant' ever see Apple producing open hardware or software, they have no need - sales are good, users are mostly happy, why fix what isnt broken?

I asked this question of a non-tech person and they said Apple knows how to create products that can be sold to the masses, and how many teens or casual users really need more than the best thing on the market. Wow! 

Mac users, at least in my experience, want products that get out of the way and make creative work easy. I've found almost no limitations in Mac software and the highly intuitive interfaces of all the programs means I don't have to break the creative process by having to learn all kinds of unintuitive ways to USE the software. 

If I need something more robust, then I go find it elsewhere. 

In the case of iWork, I wanted an office suite that made it easy to create good-looking documents since most of what I do is create reports for clients. iWork does exactly that. Microsoft Office? Not so much. Last time I tried to manipulate placement of an image in a Word document was the "last time".
