My first computer was a Coleco Adam, which I bought in the early 1980s. My second computer was a TRS-80, which I bought shortly after the Coleco Adam, and used them both during pretty much the same time period. Moving the conversation back to the OP, which was about Hal's new computer. I don't use my PC often, but I did upgrade it to Windows 10. The appearance of the Win-10 screen was much different than the previous version, but pretty much all of the same things were there, I think; just in different places. I didn't find it too difficult to learn, although I much prefer Mac.
