I've become fascinated with the yoga concept, being able to have a great looking powerful laptop that can be used in 4 different positions and also has digital pen wacom-type capability. So after much research my rmb ordered the HP Spectre 360s, beautifully designed in all aluminum (as in my subject line) and its supposed to be on a par with the retina macbook pro in many ways, plus being ale to do more, 4 positions, digital writing etc etc. Should be a nice option to the Mac, with Windows 10. Anyone out there also using this option. I played with W10 recently and its pretty nice.
