"I have implemented iJoomla Magazine, News & SEO for my clients and am about to buy Ad Agency for myself. I am also waiting with baited breath for iJoomla LMS.
In evaluating different Joomla components, there are so many options available, many of them free, yet, i find myself always coming back to iJoomla for 3 simple reasons:
1) Perfection in usability: Joomla can be a big confusing mess. iJoomla components are well thought out, comprehensive and streamlined. They obviously take a lot of time to think through and test the usability, because their interfaces are always very clean, intuitive and easy to understand.
2) Thorough documentation: With iJoomla, there is no need to go searching for documentation, only to find very cryptic, barely readable instructions. iJoomla embeds comprehensive documentation, hints and links to videos right in the admin interface so that users can directly access the information they need right at the moment they need it.
3) Flexibility/CSS Neutrality: The iJoomla team is obviously very CSS savvy and has a thorough understanding of the Joomla template community. Unlike some Joomla components that build in ugly, unusable CSS code that is very difficult to change, iJoomla's components seem to be built in a way that mesh seamlessly with any template. When they do have built-in CSS, it is very easy to access and update.
I really need the LMS solution right away and almost purchased a different solution, but i know if i wait for the iJoomla LMS, it will be a better solution long term."
