45% gain on 2014 technology is NOT something to be proud off. Why on earth is Apple neglecting the Mac line? Is it too difficult or beyond its ability for this multibillion dollar company to release new Macs at a minimum of each and every year??? --- Post Merged, Dec 12, 2017 --- Side note, the ventilation gap, at the back, looks like an afterthought. It's not fully resolved. It would be great if Apple could be more discrete about the gaps in future designs. Why can't the air flow enter from the underneath left 45 degrees and exit from underneath right 45 degrees? Rendering it not visible. The current configuration on iMac pro sees it enter underneath and back down out the back through a long out of place gap.
