The world is full of compromises that actually work really, really well. Consider the sports sedan, with its combination of speed and space. Or the iPhone in its phone/camera/music player/other stuff hyperconveneince. Or the venerable Swiss Army knife, a right-sized collection of tools that all work pretty damn well.
Yes, purity of intention is a noble thing, and there are times when there's no substitute for a Ka-Bar or a Caterham, but on the whole it's always impressive to package a few things together and maintain a high level of functionality. Sometimes those sets of tools are just perfectly obvious, sometimes they are an inspired blending of the unexpected.
