Well, although these are serious questions raising interesting problems, IMHO they don't fully cover the topic... No doubt that HC (and especially the Xtalk syntax) was developped by Apple in the same "plug & play" and "user friendly" spirit as the Macintosh. But having a prog. tool allowing to code in a syntax closed to natural english doesn't prevent to learn such concepts as variables (local vs global), loops, arrays, functions, handlers, sending messages, passing parameters, etc. All of those being typical computer science concept. The fact that X-talk syntax is far less cryptic than C syntax helps a lot in learning those concepts, especially because one can focus on the concepts themselves without being bothered by any cryptic syntax. But OTOH I've seen several custom projects developped with HC or OMO by non professional programmers : although these projects did (more or less) their work, they were totally awfull from a prof. point of view, mostly because it was clear that the above mentioned basic concepts hadn't been totally understood by the ppl who developped them, and often they had made choices and written code that was totally ridiculous, slow, uselessly complicated... And if any of these projects had to be maintained or extended by someone else, the task was almost impossible, and it would be easier & cheaper to re-write everything from scratch. So the question is rather : to which degree of complexity can a project be developped in X-talk by someone without serious computer science bkground ? To which degree the X-talk syntax isn't only a way to improve productivity of ppl with serious computer science knowledge, by allowing them to reach a greater complexity in their projects in less time and with less lines of code than, say, C or Java ?
