Tim Cook spoke at the Goldman Sachs Technology and Internet Conference, and he's shared a few up-to-date numbers about a few of Apple's platforms and services. iCloud is probably where he shared the most fascinating insight: The service now boasts over 100 million users, which is a very sizable user base. I don't know offhand how many Apple accounts are out there, but that seems like a significant amount of growth for a service that's not all that old (although MobileMe customers were obviously migrated).
Apple TV is also growing -- we've already heard this year that it was big, but Cook says that Apple sold over 3 million set-top boxes last year, and a million last quarter already. He confirmed that the Apple TV was still just a "hobby" for the company, but noted Apple still wants to see more mainstream acceptance of the streaming media device before really dumping in.
We'll leave it up to your imagination as to what the Apple TV would be like if Apple decided it was a real market instead of a hobby. Finally, Cook also pointed out that Apple is growing at a gigantic rate in the developing world, earning twenty times the income from previous years in developing tech nations like Asia, India, Eastern Europe, the Middle East, and Africa. It certainly sounds like Cook has confidently moved into a leadership role at Apple -- not only are things going great, but he definitely has a plan for the future.
