Re: Cost vs spec
There's plenty of systems like that already for you. Lenovo, Dell and HP's enterprise lines, to name but a few, have models that are bristling with ports, and where you're paying purely for the components inside. I had an office-special Dell 15" at a previous job - it was pretty dull and boring, but the specs were really good and it would survive a fair amount of abuse, and it could connect to pretty much anything.
It's not a zero-sum game: companies are just addressing buyers who have different priorities to yours; but your attitude to purchases is still the prevalent one. If anything, the higher margins from the style-led systems will make the function-over-form models more affordable.
