The question is which of these is a general purpose computer and which isn't. IMHO if what people tend to do on a platform is the same as what they do on a PC then that platform should also be forced to be a general-purposed computer and allow (in some roundabout way) arbitrary application installation.

For example, a smartphone replaces a PC for a lot of people. I even know some people in their 20s that don't own a "normal" laptop/desktop and they do most of their general purpose computing on their phones. In the meantime, nobody uses a Nintendo Switch or their dishwasher to do a quick edit of an excel sheet or access their bank account even if they are technically capable of doing so.
