All the same, all changed. (Score 1)

It's all the same. It's all changed. Yet the more it changes, the more similar to its predecessors it will be.

The OS wars have been happening for decades, yet the truly smart people know the truth - it's all the same, at the core, the processor has the same registers, the same flags, the hardware is the same, and it doesn't care what OS it's running. To the hardware, it's all a string of binary bits that are being channeled through it.

A true guru won't really be held back by the OS that's running, but rather by his own philosophical views of that particular system. In other words, while the system might be functional - even if only in the hands of him and his peers, it might not be tolerable from the point of view that his own philosophical values project towards him and indeed, others around him - who will or - perhaps - will not, be influenced by his actions while using the system in question.
