People sometimes have slow connections, particularly BB users who feel no need upgrade to the latest connection speed. The app has to be completely downloaded before it runs, unless you put external references in your PhoneGap packaged HTML, I guess, but then it would only run online. Additionally mobile browsers are often slow to execute, so loading a lot of JS can bog down your app. For a while there was a big stink about iOS only using their best JS engine in Safari and not web controls, not sure if that every got solved, but laggy HTML based apps is a big problem.
