I think a lot of folks will be bitten in the bum by this with the new setup. Apple says your "sharing" the account, but the word isn't really being used in the sense most people think it is.
There's almost a transition between 2 systems.
#1: The original goal was just to allow a user's purchase to be played on up to 5 of the user's computers.
#2: The goal now is to allow a user's purchase to be played on all their devices (I think...)
But in between we have used it differently, and it's muddied the water somewhat. Each computer can have multiple iDevices. People have shared AppleIDs - my wife and I share an ID, why wouldn't we when we are listening to music on our single speaker system. I sent my brother a copy of a couple of my apps (he's authorised).
If you want to, the current system even lets you sync bookmarks/calendar/address book using one AppleID, iDisk on another ID, purchasing on a 3rd ID. It all works within Apple's usage model - but when the value of having a single AppleID increases, and if Apple starts storing a single ID in a device - then a single iCloud account is storing my safari reading list, book bookmarks, app settings, music/app/book purchases, my documents, and email - and it starts being really useful for me and my wife to have separate AppleIDs.
So I see where they're going. And it's probably closer to their original intention of how AppleIDs would work. But right now, there are problems with the past AND problems even in Apple's model. For example, if we have a separate AppleID it'll kill homesharing - I want my AppleTV to play content from iTunes on my MBP OR iTunes on my wife's iMac, and I want both our iPhones to be able to remote control the AppleTV.
It'll be interesting to watch this progress. For now we can probably get away with sharing the AppleID a little longer, as long as the OSes allow us to have separate emails.
