Far more 'for the masses' than the Surface Studio which is three times the price, though. And, of course, at those prices, three times is a LOT. Everyone seems to be of the opinion that home desktops 'for the masses' are on the way out anyway, so those who will be buying iMacs (if they continue to exist) in future are likely to be in the 1%; the Surface Studio buyers will probably be in the 0.1%, though.
At those prices, more like computers for the 1% - a niche almost as small as illustrators.
