Macs are really easy, they are designed to be easy !

Logic is great because it comes with just about every plug-in you could want, mp3 encoders etc etc (unlike Sonar). It is very stable however the interface is slightly different.

Example, the input meters are not as readily visible as they were in Sonar, I ended up clipping the top of a bit of guitar I was recording last night. Avoidable.... yes !!

Also when you are bouncing and exporting you seem to have to manually set the end of the song. I didn't have to do this in Sonar ! their may well be fixes for these things however it is just a matter of spending the time with the program to get familiar with the way it works what everything is called and where it has been put !
