Unless the person was mentioning my name saying how "I" was stupid for owning this or that machine or how "I" paid too much for a machine, I could care Less. It would have to be Personal before I took it Personally. To Each Their Own on opinions of game play and worth.. Just their opinion and they are entitled to it.
