By accomplishments, do you mean Apple's current products? Of course. If you mean Apple's concept videos - I don't know, since I haven't seen any.

Concept videos usually aren't realistic, or even preferable, since they have to convey what the technology can do simply through video. In reality, it'd probably be more discrete and easier to use. The advantage concept videos have is that they simply demonstrate possible uses of possible technology.

That triggers a few questions if you're creative: Is this possible to achieve with today's technology? What problems would things demonstrated in the video solve? Is it possible to solve the same problems, or sub-problems, with today's technology? Can I develop this concept further, take it in a more useful/fun/futuristic direction?
