I recently purchased an iMac on craigslist and set it all up with the apps I've downloaded from the App Store. This got me thinking. How do larger families with multiple Macs manager App Store purchases? Does everyone have their own Apple IDs and for big software purchases share Mom's or Dad's? Is there a "family Apple ID?" I kind of have the same question for iTunes but a $.79 song doesn't bother me as much as a $79 App. It'd be nice to have a family ID but how would that effect iCloud and iOS devices? For me, I'd like to keep all my iOS stuff separate from everyone else's.
