To me its a bit like going on holiday and renting a car with the steering wheel on the other side. Takes a little getting used to, but whole populations can cope with driving on the right, or the left. Smalltalk has a beautiful simplicity, allowing one to express really complex ideas, which to me seems like a super-power. But being image-based can be a pain especially when working in large teams. Merging in everyone's changes could be a PITA.
