MEPIS has released two versions of Linux. SimplyMEPIS is designed for non-technical end users. ProMEPIS is designed for more technical users, administrators, IT professionals and web developers. LinuxBuxinessReview has had a look at ProMEPIS.
The review concludes that
ProMEPIS, like SimplyMEPIS, ranks at the top of free Linux distributions. I am running MEPIS on three of my personal computers. While I have purchased copies of most of the popular desktop distributions, I prefer to use MEPIS Linux. ProMEPIS is my current installation of choice. My wife is using Simply-MEPIS. Note: Mepis is following an aggressive upgrade schedule so the differences mentioned between Simply Mepis and Professional Mepis are narrowing.
