And I like it's style, and Windows won't cut it, so for me the trade offs are okay :)
Hence, depends on your definition of better. Computers are trade offs. Always have been. Your choice of trade offs is not inherently better than someone else's.
(this is academic, btw, I'm not getting any of the computers in question)
All computers are trade offs but when you start trading sensible things for appearance then it's just idiocy.
It's the Ugg boot of computers. Looks pretty and keeps your feet warm but you can't get it wet and it isn't waterproof, they fuck up your feet and fall to bits.
I'd rather have a pair of Berghaus explorers, warm and dry feet and for them to still be on one piece after a 20 mile hike (HP Z820).
Don't really care about the OS - you can get where you need to with virtualization.
better as in not needing separate power supplies and cases to have reasonable storage options. better is not needing to buy a new machine (I know, not confirmed but they never aren't offering) to upgrade components. better is having a user upgradeable storage (the ssd is not user upgradable even with tricks according to some).
While it certainly is an interesting case, stylish for some, its pure form over function. They have essentially made a Mac Pro Mini / Mac Pro iPad ... as in what you bought it what your stuck with. Want to upgrade to a new processor or newer video card, well buy a newer machine.
I have nothing but contempt for the Mac Pro design - it's style over substance to the extreme.
