Ages ago I found the remains of an old PC and brought it back to life with Ubuntu, which is how I got into Linux. You can probably work out what happened next: Ubuntu then introduced Unity, and much as I loved the colour scheme I switched to using Mint for the resurrection purposes. One afternoon I set up dual-boot of both my Desktop and Laptop with Mint, installed Cinnamon and haven't looked back.
After a minimal amount of tweaking and much happy customisation, Mint is now my 'go to' OS for pretty much everything, apart from Skyrim and music production (although having said that Renoise is great, and I'm getting to grips with Pure Data, but I'd struggle without Orion and Komplete).
Whilst here I'd very much like to say a big thanks to Clem and the Mint development team and community for producing such a wonderful piece of kit. It's really helped me rediscover the pleasure of using my PC. It's the attention to little details I like in Cinnamon: for example one of the first things I did when setting up my DE was to change the 'Menu' name to 'Start' (Hahaha...) and put a little .svg of Tux as the icon. And installing Mint was easy enough, the only issue I had was with my M-Audio Delta card on my desktop (since solved).
I've got Aptana and Bluefish for web dev, Spotify and Miro for music and podcasts, Desura client for games (Eschalon is great, as are Osmos and Braid - loads of Indie games are coming out for Linux on the Humble Bundles) and more desktops than I can shake a stick at, so I'm really pleased with this whole setup.
Really, Mint and the whole Linux thing is amazing. I'll have to have a think about ways I can contribute.
