I don't like how skeuomorphism turned into a dirty word. A skeuomorph is just an unessential design cue a derivative takes from the original. They can be entirely ornamental (like the dumb faux leather of some of the latter day Jobs-era iOS apps), but they're quite useful as affordances. There's no particular technical reason why you'd prefer any one particular graphic design for tabs over another, but the separator-style tabs make the association between tab headers and contents much clearer than the new design. Likewise, there's a lot of value in the Numi/Soulver style of calculator apps for power users, but common users are better served by the skeuomorphic physical calculator design, which is perfectly functional and much more familiar to most (though this may change as younger generations are less and less exposed to traditional calculators).
