How to go beyond 5 authorized computers?

Question

I currently have a desktop, a laptop, an old laptop with a crashed hard drive that was authorized, an IPad2, and Ipod, and an IPhone and a desktop at work--all of this I want to authorize to share information across iTunes and the Cloud. This is 7 computers, and I'm planning on purchasing a Mac Pro laptop. How do you get past the limit of 5 authorized computers?  Is there something you can purchase to go beyond the limit of 5 or what?  And...why is there a limit of 5 in the first place?  My father has 7 computers (1 PC, and the rest are Macs).
1)  Why is there a limit of 5? and
2) how do you get past the limit of 5 if you have more than 5 computers you want to link together?

Answer 1

As John has already said, it's an agreement with the record companies. At some stage, someone has decided that five is sufficient.
There is an obvious question here though.
Why do you need to put the same content onto all these different devices? What, for example, is the point of having the same music (or whatever) on a work computer as you have at home? Since Apps cannot be used on a computer, you don't need them on two different ones. Since you have an iPod - and an iPad, you have your iTunes Library with you, don't you? So why the desperate need to keep putting it somewhere else? You cannot Sync an iDevice with two different Libraries.
One thing you do appear to have missed; you can deauthorise the laptop with the crashed hard drive. That will save you one device. (Actually of course, you need to deauthorise all and then re-authorise just the devices you want, up to five.)
You may have noticed that I do not sympathise with your point of view. Personally, I don't see the need to ask Apple about this. If anyone needs to be asked anything (in my opinion), it's the record companies and the music business.
Why don't they devise a replacement for the outdated concept of copyright?
Why don't they allow us to pass our purchased music on to our family when we pass away?
Why did a certain musician (drummer) believe he was entitled to accuse his fans of theft while he was sitting in luxury next to his swimming pool in front of his very large house?
