During its Q1 2012 earnings call where Apple announced a record-breaking holiday quarter, CEO Tim Cook also announced that there are now 85 million iCloud accounts. What's impressive there is that iCloud is just three months old, coming in as a replacement for the aging MobileMe, so that's a tremendously positive number as it pertains to user adoption. In fact, that 85 million number is 50 million more than iPhone 4S units sold.
