Haha, let's play on -- though you still have en edge!
Ever have seen a handheld of Psion "Epoc/16" line? Epoc 16 was a quite nice
operating system, which featured among others preemptive multitasking, and,
what's important here, dynamic ObjC-like OO system. (It used explicit C
coding though, and selectors were defined statically, so you written things
like "send(object, SELECTOR, arg1, arg2)").
Well, the thing run on, IIRC, 4.75 MHz V30 chip, with 128 or 256 MB RAM.
There was a quite nice GUI there, even!
