I have a Chrome-specific web app that uses jQuery to help handle the styling. There's nothing very advanced in there; it's all things that could've been done with standard JavaScript (basically adding/removing classes on the fly, changing position values etc.), it's just easier to type and read using jQuery. Is there any actual point in upgrading from 1.9.1 to 2.0.2 (and each subsequent version) and going through the effort of testing everything when it is stable and works beautifully in 1.9.1?
Edit: I should add that no jQuery plug-ins are being used either.
