limits it, drives it and charges a premium because all the drivers mostly work. Microsoft has the same thing, its called a xbox and is considerably more expensive than a laptop.
I have access to knowledge to hack registries. My earlier point was that I have been pigignorant of having to do anything with my lapper. Of course I dont download, click, get phished (well mostly) anything I am not sure of. The box works, doesnt require any config stuff or things of that nature.
I use it too keep my books with gnucash.
research the intarwebs
download very specific software to test for tools in aid of system administration.
read garbage blogs and news sites.
email and here.
So I dont really do intensive stuff, but have not had to figure out why it is not running at all. It just works, like Mac just works but without the sticker shock.
