I see the "innovation" in this thread switching between true innovation and frustrations over the diminished quality of newer pins. Can't argue the quality part because I've never owned one (yet), but what sort of innovation do you think Stern should have accomplished by now? More interactive toys? Video games on the playfield? Actually, that second one sounds kinda cool...though I'm not sure my brain could handle playing a video game and pinball at the same time.
I like pinball art more than the Photoshop stuff as well, but I think that's often more of a personal preference. They had no choice but to use artwork before Photoshop, but I'm guessing Bally, Williams, etc. would have embraced it at least a little bit if they could have.
