Good summary. It's worth pointing out that Borland's Pascal had already diverged from other dialects, including Apple's, and when they tacked on the OO extensions from Wirth's ObjectPascal/MacApp, they diverged further. MacApp is interesting in itself, but I'm not sure how much involvement Wirth had in its development. Delphi certainly owes a lot of its design to it, but nailed the visual UI builder in ways that MacApp didn't (and in a way that Interface Builder never has). Apple actually kept supporting and updating MacApp as late as 2002 (Photoshop was famously written in it) [1]; it's one of those beautiful niche things that eventually die, but keep a lot of people magically productive for a while (just like Delphi, coincidentally).
