jQuery Mobile is a great technology, no doubt it can be an integral part of the future like jQuery is today. However even if the 1.0 version is out after more than a year after the alpha has been launched, it still feels like a very young product. There is enough posts and beginner tutorials around the web about the greatness of jQuery mobile. But not so much about the hurdles of jQuery mobile integrated in other systems.

Before using backbone when working with a list of html nodes I always made it my duty to append them only in one big chunk of text. Manipulating the dom is slow, it triggers a reflow of the page, this is costly even on small lists, specially on mobile.
