Its a technical masterpiece, very slick, generally very reliable.
However, even if I were willing to invest the money I have two objections -
Firstly the they're charging an eye watering price per gram for the equipment, that they charge because that's what they think the market will sustain, not because that's what the Taiwanese electronics costs them.
And second, my real objection, is because I love the mechanical simplicity of bicycles. GPS is about as far as I'm willing to go down the flow of electrons on my bike, and there are reasons why I'm not entirely comfortable with even that. Hell, I'm the guy that doesn't have a smartphone.
Fundamentally, its reliable, excellently performing gear, so if you do fancy it there's little reason not to do it. The real question is whether it is compatible with your cycling ethos.
