That is true. Given the 'nicheness' of a scanner product, it is fair to assume some level of universal consistency. Your example refers to hardware differences but the argument being, for example, is that if an LG branded TV receives a firmware update in Europe, because there's changes to internal apps, then that same TV in America will too receive the same update - it occurs frequently with smart TVs. Obviously, this is very simplistic and commercials regarding electronics is much more complicated. It's just disappointing not being able to receive improvements, fixes and new features for a highly comparable product.
Apologies, I've somewhat digressed the thread's topic. Regardless, I want to make it clear that I'm not on a witch hunt for Joe and I very much would love to have a pretty waterfall feature and I'm very much jealous I can't haha.
