I've done a bit of reading on NEON and I'm curious how often it's used. Certainly it seems useful, but even ARM seems to be heavily pushing the media [de|en]code capabilities of this SIMD implementation which is something that may very well be handled by a DSP (though in a much less generalized way). But is it generally used outside of this?

Does anyone have links to NVIDIAs rational for leaving NEON out (beyond space savings)?
