It certainly wasn't my intention to dissuade people from experimenting! My comments are definitely directed towards those who are experiencing difficulty and frustration and hopefully seen as potential ways to preemptively avoid such things. I would hope those who are purposely experimenting aren't also frustrated... as difficulty is to be expected, even welcomed!
As far as minimalism goes, I still say that a low power laptop CPU and any HDD, especially an external HDD, is just going to cause unwanted pain when dealing with the block chain. Is it possible: sure. Is it going to be smooth: doubtful. Can an expert make it a reasonably smooth experience: yes.
