Reason I'm asking is: I have an old Centrino laptop as well as an RPi2 and RPi3. The Centrino is so much faster than the RPi's, it's not even in the same league. And as long as the Raspberrys are married to Broadcom, I think it will take quite some time until we have an RPi that has similar speed like my old Centrino. Don't get me wrong, I love my RPis, and if my old Centrino breaks, maybe I'd do something similar, but I'd never trash it while it's still working. Just seems wasteful to me.
It could also be not only about pure speed - look at what even the RPi 1 can do in terms of media playback. My (working) Centrino laptop can just barely play youtube html 5 videos. If you want a small mediaplayer (remember those portable DVD players? :P) this sounds totally viable.
