Umm, yes it's about resistors too, it was mentioned in my very first post.
My original question is why don't they mark SMD capacitors, when it's very 
common to mark the same size SMD resistors.
So Sergey's remark is perfectly valid. It's common to mark cheap resistors, 
but it's not common to mark more expensive capacitors of the same size - 
why?
It's clearly not about cost, as Rich mentioned.
I'm assuming the reason is technical/process related, and not historical 
etc, but I'm not sure, so that's why I  asked.

Dave.
