I blame Lenovo for the Surface's success. If they had made the Yoga Pro Line pen capable, the SP3 would never have gotten off the ground. Think about this. Lenovo has a HUGE mega-hit with the Yoga Pro Line and they hamstring it for business users by leaving out the pen, thus opening the door wide for SP3 to fill a need? All this to force us to pay more for their Yoga Thinkpad (i.e., inferior) product?
MS smart. Lenovo so so dumb.
P.S., I had a Y2P which I LOVED but sold it to buy a SP3 because of the pen flexibility. Other than the pen (ok, and the 3:2 ratio), I liked everything about the Yoga 2 Pro better than the SP3. And there you have it Lenovo you stupid stupid people.
