Hi

It is not that hard to switch from applications to applets and vice versa. Applications and applets have their pros and cons, we have already spoken about that here. Applets are easier to use for the final users as there is no explicit install but their support is not consistent on all web browsers and there are some limitations. Applications are a bit less easy to use for the final users but you have less limitations and you don't have to worry a lot about the browser (it is easier to make a stable game as an application than as an applet except if you make something really simple without hardware acceleration).
