Is there a place where I can directly ask experts or experienced users about alternative apps of my need. I have been making my mind about complete switch but few of the most used apps from Mac holds me back. I wish someone can suggest me a decent alternative to those apps. I must also add that I will lose several licenses of purchased apps in the process but I am willing to make that sacrifice. I wish I could find a reliable way to keep running those apps in VM.
