Do you really think that anyone apart from RISC OS users really reads drobe.co.uk or comp.sys.acorn.*? Sounds like a load of nonsense to me.
I do agree with you that people emphasis the negative, perhaps too much. But I think this stems from the fact that if it works then it's hardly worth talking about. If it's broke then kick up a fuss and get it fixed
And any way, when you think about it, do you really think that your above comments will in any way stop people doing what they want?
If you want to show the positive side of risc os, point people to the drobe headlines. These guys do a great job promoting risc os. (my JGZ approved positive comment)
