Apart from size and many functions that translate 1:1, where it really doesn't make sense to use Jquery (time to learn ?) there are two extra factors: 1. the extra http call to load a library, that can be optimized 2. licensing, some company cares about that and avoid the the hassle of having yet another license to understand and manage, there are costs involved I've seen thousands of js snippets using jquery just because the developer doesn't the pure js syntax, or because he is used to start from adding jquery. very good page indeed, thanks for spreading the knowledge.
