I'm happy enough with AROS.
It exists, it *is* open source. Its written by friendly people. It already has enhancements vs 3.x. People can actually have a say rather than dreaming about having a say.
Its like having 2 doors leading to the same place, one open, one locked/chained and with a plethora of barricades.
Yet for some reason, time and time again people seem to disregard the open door and ponder how to get through the other.
In regards to a task manager and the ability to free memory from a crashed program, its been possible for decades. My preference is Scout.
