I like it
I've been using Jetbrains IntelliJ Idea for Java for a few years now and would never go back to Eclipse or any other IDE. It's a real eye-opener just how much better it is than anything else out there. I have not done C++ in years but I used to use Code::Blocks for C++. Recently when I had to look at some old C++ code at work I fired up Eclipse CDT - which is the standard here... and immediatly shut it down again (well as fast as I could... Eclipse takes forever to start up and shut down...). So I grabbed Code::Blocks and did my work in there... but compared to InelliJ Idea Code::Blocks felt really primitve. Not much of a step up from Notepad. I never realized how wonderful the tools in IntelliJ were until I didn't have them at my disposal.
A little while after that experience I gave an early Alpha build of CLion a spin... and it was pretty awesome. Glad to see it finally released into the wild.
