Possible to use JqMobi for both desktop and mobile browsers?

we have a site that is running on Jquery and Backbone.

But it is rather slow on the mobile, but i do not want seperate bases for the desktop and the mobile.

I was wondering if jQmobi runs well on desktops as well? I do not care about supporting IE8 and below.

It's webkit only, so if you only care about Chrome/Safari it works fine, but it does not work on FF/Opera/IE currently.
