how is this different from the likes of jquery?
edit: it seems the library is similar in terms of dom manipulation, but the compiler and templating system seem to be the major differences?

This is a very big deal for JavaScript developers because it is like having JSLint, YUI Compressor, and Chuck Norris rolled into one.
It won't actually make your JavaScript much faster, if it does at all. The major benefits are the exclusion of unused code, and code in-lining where possible. This helps a lot in terms of cutting down loading times, but your code is still only really going to be about as efficient as it was before.
But do GWT and Closure use the same technology, that I don't know.
