Dan Frommer:

In an informal flip through the Fortune 500 companies, the only industry that seems to come close to Apple’s current growth — at its size or larger — is the oil business. Chevron, for instance, is twice Apple’s size and is growing at the same rate.

There will be a point when growing at the rate Apple current is will be very difficult — if not impossible — to achieve. Luckily, Apple seems to not be close to such a point.
