I really wish that there was a license/version/build marketed to hobbyists:

>Call or Email for Pricing

and the upgrade pricing is four figures (per set per year I'm guessing?).

Ages ago, I actually bought a Smalltalk for Windows compiler, but never got around to doing anything with it (which I regret) --- I suppose I should try Dolphin SmallTalk....

Dad is true Smalltalk believer, used to use visual age, instantiations etc but is a happy user of pharo nowadays which is free, opensource and under active development so could give that one a try.

There is Pharo (and Squeak) as a free SmallTalk.
