The 2010 editor is this one, which is not available on any Wikia wikis I know of yet (it's not the 2006 toolbar or either rich text editor available on legacy and it's not the 2017 VisualEditor).

...Also, where are you finding a laptop that small? That's just a curiosity question. XD When shopping for my new one I couldn't find one less than 14 inches (except maybe ones without any sort of respectable amount of hard drive space?).

The 2017 VisualEditor was developed by the Wikimedia Foundation, the people behind Wikipedia (not Wikia/Fandom), and isn't in alpha (though Wikimedia still considers it in beta o.o). (And previewing is available on it as long as you're in source mode.)
