I read highlights, and I'm concerned about the system's gaming capabilities. It's using a next-gen low power AMD Jaguar CPU. Not highend (i7 or AMD FX), not mainstream (Pentium/i3/i5) but low power. Think Intel Atom. It requires installation of games to the HDD (games stored on Blu-ray disks!), and MS only gives you a 500GB HDD. Honestly, I'm suprised they didn't use a SSD. And why the hell does it need to run three OS'es at the same time? WTF Microsoft!
And there's only 8GB of DDR3 (compared to the MUCH faster GDDR5 of the PS4) shared betwenthe CPU, GPU, your game, 3 operating systems, and whatever multi-tasking you are doing.
