Boost.SIMD library looks very promising! I would expect that within a few years, SIMD instruction sets continue to become more regular and useful, and that tools like Boost.SIMD will become more widely available and useful...and who knows, maybe even a part of C++... So I'd rather wait until that happens before diving in to all of the current muck... Hopefully, I won't be too old to write code :-)
