Surely being simple is the worst scenario, as the boredom of coding a simple feature must surely lead to the "ooh let's add some functionality to keep it interesting" mindset.

Simple is only boring if it's long-winded.

That would imply that you're cloning identical drives though, no? Anything more complex like resizing partitions, different alignments etc is a different question.

None of the devices do that?

Well, perhaps some of graphi's thousand pound ones do, but the rest just seem a simple push a button and get a clone.

Even if they did do partition enlargements and stuff, is it actually anything more complicated than maths?
