I've only been using Manjaro for about a week now, but I've been using Linux exclusively for almost 3 years. I started out with Ubuntu, as that is what everyone was saying was the best to start with. I then got tired of the bloat, so switched to Debian. Debian is great, but updates can take forever.
Last week, I decided to try something new and almost completely different. I took a look at the Manjaro Mate ISO, and haven't looked back. On this system, it only takes about 15-20 seconds from turning the system on, to having the desktop in front of me. It has been a great experience.
I hope that I'll be able to help with some of the questions in the forums, but still working on things such as pacman. It's a lot different than apt, but also a lot faster.
Keep up the great work with Manjaro. I've been having a great time with it!
