I have never been impressed enough with an extension before to bother reviewing, but this one deserved the effort. I've been using Joomla for client web-sites for several years, but I'm completely new to 'mobile' site creation. Having used another popular mobile "system" (several modules and plugins combined...) previously, I was never happy with the results - and the latest version was full of quirks and problems. I wondered how J-Touch, a template and 1 plugin, could possibly serve my needs for a news magazine site that receives almost a half-million page views a month. WOW - installed, tweaked the HTML code and added a custom graphic for a header, and had a beautiful mobile site in less than 30 minutes. I did have problems with the menu, but I suspect that is an issue with the script-heavy main site template I am using (I had the same problems with the 'other' mobile extension as well), and since I didn't want the menu anyway, I didn't seek any support - and found it very easy to remove that part of the J-Touch template. The combination mobile-app / mobile site I created has made for a VERY happy client AND a VERY happy developer! For quickly converting your site to a mobile-friendly version, I would highly recommend J-Touch as a fast and simple solution.
