The amiibo function will work exclusively with Nintendo platforms only, as you'd expect so aside that the figures look pretty cool and its functionality will make them playable in Skylanders: Superchargers. A shame that the actual amiibo functionality doesn't allow such thing, but hey, if Activision brings in the rest of the amiibo collection then they will.
Just imagine playing as Mega Man, Sonic, Ness, Lucario, Rosalina, Greninja, Marth, King Dedede, Shulk, Meta Knight, Villager and all the rest!
