I'm one of those whom share an apple id with other family members (the kids) so they didn't have to pay for apps twice. What I am still attempting to figure out is how I will go about also having my MobileMe which is a separate id, how this syncing is going to work with all these i-devices in my household not including the three iPads I use for work personal and development.
I also attempted to buy more storage under iCloud settings and it is not available right now.
The way I figure it, if all my i-devices aren't going to be able to share the Apple ID for app purchases with iCloud login, that I will have to make them all create separate Apple ID's which only raises more questions.
My main one being, Will each iOS5 device have 5 Gigs of storage or is that 5Gig only per Apple ID login or account. Too many questions not enough answers yet.
Im contemplating placing iOS5 for testing specific app usage & doc sharing across all my daily devices including the iPad 2, just to get moving along and be used to it all by the time it all comes public and by doing so hopefully have tons of experience to be more apt to deal with these issues on public release.
I would not be so inclined if this was not such a solid build, I would only keep it to the testing devices.
