I've been using Ubuntu since 10.04 and been testing 12.10 for the last few months. I'm an avid fan of Ubuntu/Canonical and think they do a great job.
Introducing Unity was always going to be a big decision and cause controversy. But I admire their commitment to move forward and do what they thought was best. As with any bold new task, there are going to be bumps in the road, disagreements and critisisms along the way. But with enough time, feedback and improvements, things can work out very well (think KDE 4). So I stuck by Ubuntu/Unity, tested the development versions, reported bugs, voiced my opinions and suggested improvements. Unfortunately, with the near release of 12.10, I now find it hard to agree with the direction the project is going in. It's a shame because I see big potential for Unity, but I simply can't see it happening.
So last night, I decided to give Linux Mint 13 + Cinnamon 1.6 a go and... wow! It's exactly what I believe a desktop should be. I can see everything little thing has been well thought out and it just makes sense. Everything is in a logical place, allowing me to conduct all my tasks with speed and efficiency. It just looks awesome, well polished and professional. I feel I can recommend this to everyone I know (I couldnt' say that for Unity) and they would love it.
But best of all, you look like you have a great community that's friendly, helpful and that genuinely listens to one another. Each voice goes into the success of the project and that's the kind of community I want to be apart of.
As a small token of my appreciation, I'd like to support the project by becoming a bronze sponsor. Keep up the good work guys!
