We've known for a while now that iPhone 5 won't be coming out this month, as it has for the last four years, but this fall, when iOS 5 is also scheduled to ship. Whether one delayed the other, or factors such as Verizon contracts, component shortages, engineering hours, or some combination of factors we may never know, but now rumors suggest new Macs are similarly on hold, this time waiting on OS X Lion before they ship.
