It looks like you are either being paid secretly by Microsoft to post all this or you are trying to impress the HR manager of Microsoft to get a job of spokeperson at that company.
Else, any person in his right state of mind will agree to evidence presented by experts in their field.
I dont want to go into the question of who is affected how much by using what software because I beleive my time and energy is to be used more wisely and not in mundane debates and pointless link-collecting.
I have NEVER claimed that any open source or else software is free from bugs.
Its like:
using IE is like getting bashed by 10 guys,
Using FF is like getting bashed by 2 guys.
Now what you choose is upto you........basically, iMav, you love the software vendor, not what the software does and how it does. But I like what the software does and how it does, I have no time to love vendors.
