On the other hand, when working properly those tech advances are just that a little complexity but do contribute to driving our cages a lot easier, but takes away from the "skill factor"! I think I saw Gunk Engine Brite in a small can as well as a spray, I think they even used a version of it at the coin operated car wash...as late as 7 years ago.
As for the good ol' stuff, I know the computer keyboard I am using has slowed my touch typing ability and accuracy considerably from the old mechanical typewriter days in high school, but would I want to go back?...not without HDTimeline in the mix...nostalgia is a good thing, but only to a point!
