The numbers seem stellar by themselves, but Asymco created a chart of cumulative sales of Apple computing products which really puts them into perspective.
For example, Apple sold more iOS devices (156 million) in 2011 than it sold Macs (122 million) in 28 years of their existence.

What makes these figures even more amazing is the fact that Mac sales are actually rising fast: 2011 was the best year for Mac sales in Apple history.
In fact, all the major hardware product categories in Apple's roster are selling extremely well and show no signs of stopping. We can't say what this chart will look like in a couple of years, but right now, sky is the limit for Apple.
