I really like using jQuery UI in my web applications. But even though jQuery UI is very well tested there are some potential issues to keep in mind. One of those is using the jQuery UI controls on touch devices like the iPad. With these touch enabled devices becoming more and more popular support is quite important if you don’t know you exact client configuration. And for that matter, even if you client has standardized on a specific browser, let say Internet Explorer 9 for example, you may notice that there are in fact lots of other “unofficial” devices being used.
