When I got the computer, it has already come to be a reflectionaly machine. But familiar friends, who were also familiar to it, were using it and I found it be interesting. I used it for procreating artificial life, which were my first programming. It was amazing to feel that lots of outputs were emergented due to few inputs. At the time, I was unconscious of emerging science though, that's a fundament of the emerging mathematical approach which was compensable for reductionism. Ipso facto, von Neuman said that the computer had a possibility to be an automata in both of nature and art (artificiality).
If you would have an intention to use a petite puter as a stationery, I should recommend PDA and so on... If you would like to do computing essentially in a nutshell, the itty-bitty puter could have come to be one of selections.
I never assert though, but, for such a task, such a puter is not too primitive.
With that, as one such, I had used it regularly for programming experimental phase of something of adaptive complex system and opusculums for presentation. After all, it's a carry-along puter just like a small sketch book.
