The new inspector is totally unusable. It doesn't seem to solve any of the normal workflows that you run into doing front end dev work. Like inspecting source, looking at the console, looking at network traffic, request/response headers and contents, etc. The console lags unbearably. Even printing an object, it gives you a nice view of the contents but opening it might take 10 seconds. The list goes on. Fortunately I don't have to debug much js at the moment but I switch to Chrome when I need to. Very glad to be able to switch back now with just WebKit because I do prefer it as a browser.
