One thing I don't like is that my modem has an issue since the other day and needs to be replaced.
My Mac Pro doesn't have wifi, so I can't jump on the neighbors wifi for this download (with their permission).
My iMac has wifi and does download this chunk just fine. However, it says of course "different machine, we can only upgrade if we delete all the apps, contacts and email will be saved, not the rest".
Yeah, very annoying, hehe. Why would it matter which machine you synced it up first with? Sucks to know that if you buy a new computer -and even with same iTunes- that you can't just upgrade, but will lose your apps.
Losing apps is temporary, I know, but who wants to play 150 levels of angry birds *again* just because the preferences or results weren't saved? Not me hehe.
