Now that Atmel Studio 7 has been released, *sigh* I'm very disappointed that there is no non-Windows version (OS X, Linux) of Atmel Studio.
I suppose it's not surprising as Atmel Studio 7 is tied at the hips to Microsoft by the use of Visual Studio.
Suppose we'll just need to keep waiting...
At least the latest version of TI's Code Compose supports OS X, yeah!
