I really dislike the "collection of numbers that transforms in this way" definition of vectors, tensors, etc.

It is not totally without merit if you consider the tensor bundle as associated to the principal bundle of linear frames. However, that's hardly suitable as an introduction to the topic.

It's probably the Wikipedia introduction, though...
