I’ve been a user of proprietary products for a very long time without giving it much thought. In fact I’m writing this on an iMac with OSX as the operating system. I own this iMac for at least 5 years and it is a nice machine but as time went by something kept nagging. I used to believe that for good reliable software you had to pay money. If software was free (as in gratis) it was probably unstable, user unfriendly and unpolished that it wasn’t worth any money. At least that is what I thought.
