My views on open source vs proprietary software : what do you prefer aching your head all the time or aching your pocket once ? !!

Pocket once? You haven't met Visual Studio or basically Windows yet, I presume?

How about aching my head once to set it up and then forget about it? For free? And with no moral concequences(yes, I am that sort of person). Supporting companies that see you only as a wallet = idiotic. Supporting people and ideas = the right thing.

@antoni4040 yes you are right in your situation. I am an embedded systems developer and used to get lots of hassle using open source applications. It's my average views preferring to the application software rather operating systems.

I guess it's time to get some glasses, then ;)
