Hardware

Not completely. I do remember when they tried to make x86 processors for phones, and I also remember how they very much failed to gain a foothold in part because android was more based around arm, but also because the power efficiency wasn't really as good as existing arm chips in phones. However, it is a pretty good testing point given that mobile devices like phones have to have the most efficient chips in order to have a decent battery life, and yet the interest in them more or less dried up years ago. And before you point at laptops or tablets, most of that advantage is mostly that windows on arm sucks both from efficiency and compatibility perspectives, so x86 is the only real option.
