> There are installations which don't support ECC, usually due to hardware limitations
Isn't RSA much more computationally expensive than ECC? What hardware can do RSA but not ECC?

EDIT: Unless you're referring to embedded systems that can't be updated?
Actually, not just embedded systems. There's HSMs (hardware security modules) which also can't be updated to support new functions. Often this is because the underlying primitives have been implemented in fixed-function hardware to prevent timing, power and even RF analysis.
