> faster than many LAPACK/BLAS implementations

IMO this is worth very little; as long as there is a heavily optimized version written in C/assembly (ie MKL), the fact that Julia might be faster than standard-but-slower versions like OpenBLAS doesn't actually gain me anything as a user.

Some people want to use their own types and number formats, so it can potentially be very useful.
