I am soon due for a new PC... the thing is over 3 years old.
I am using my current windows machine for my software music setup, mostly ableton live, cubase and a broad range of VST's and its rockstable ....... Never had any crashes in over a year and overhere at home i only restart every few months... Next to music i use it for most of PC related stuff.
So Performance and stabillity are not an issue with windows...
What other reasons are there to switch to a Mac?
