I live in Rosario , Argentina, and in last life was a Industrial Chemistry.
I found this marvel named Squeak searching net for material for my students.
Buy Mark Guzdial book and "On to Smalltalk" from Winston.
Lucky me, this was before Argentine crisis and our credit cards are rejected outside here.
In April , with Emilio Oca and German Boccoleri we did a comercial app for one Compaq iPaq 3600.
Reading work by Aaron Reichow (dynapad) and Yoshiki Oshima (reduced images), I cook "SqueakLight", a minimal Squeak 3.4 based what in last form have only 3.7 mb and still let do some programming, having Morphic and last ajust to app.
