The use case is very different here thought. For a handheld game console, it really has to work forever (or as long as the hardware lasts) without a single issue or ever requiring users to fix anything. The competitors here are nintendo consoles, and the playstation.

It's not acceptable to say "oh its ok you can just open the terminal to fix and I haven't had an issue in 2 years". It has to be essentially perfect or able to recover itself from any kind of software fault without much user intervention.
