I've had 10 days to use any slowdown, I handed my License Office 365, all apps look great. Power is well appointment, the mem are essential 8gb ... Autonomy unlike other comments is excellent, the same as my MacBook Pro Retina 13 inches. I think even leave aside, the touch is top, bright screen is normal for a touch screen (I do not understand some reviews). The trackpad does not answer, the wifi works everywhere, 4 different places this time. The concept Yoga easel tablet PC is top, hoping that hold the hinges. The ultrabook perfect for me with the tablet function. You can read reviews on digitalversus, he did not 5 stars for nothing with a standard 500gb HDD, so with the 256GB SSD is really perfect. The finish is very good, maybe not at the level of the mac, but it is a PC of very good quality made in china as the "apple". For me it is the WIFI No, not at ac (Realtek card RTL8723BE). Just to finish the touch is very responsive and pleasant.
