I think Fuchsia is aimed at more then just mobile.

Honestly I have high hopes for it, mostly because I like the colour ^^.

"The GitHub project suggests Fuchsia can run on many platforms, from embedded systems to smartphones, tablets, and personal computers." ("Google Fuchsia - Wikipedia" https://en.m.wikipedia.org/wiki/Google_Fuchsia)

Edit: fixed spelling of the name of the colour.
