I've been a Linux user since 2001 with Corel and then found SuSE, wow... Been a consistent openSUSE user ever since, I found it the best KDE distro out there, not overly technical but I can manage my way around the WM's fine. I loved Gnome until 3, love the interface just my PC doesn't, and I'm not overly keen on all the variants so back to KDE. I'm really impressed with they way KDE has come of late, was running openSUSE 12.2 until a few days ago and it's great and I'm looking forward to the next release...
I've gone back and forth to the Buntu distro's but have always found them lacking and getting more unreliable, and lack of configuration ease like YaST which in my opinion is the be all and end all of config tools, guess I should really learn some more about the guts in the console?? openSUSE has never let me down whereas the latest Ubuntu's have been disasterous for my PC. And then there was Mint 14 KDE... A few days and still going strong, fast, reliable. I may be a total convert yet hehe.
Anyway, doesn't matter which distro, I'm aware of the free v's nonfree arguments, I've used Linux for over five years exclusively (except some minor windows useage due to uncooperative mobile phones etc) and love it.
Thanks to all the Mint developers and testers and happy new year.
