Summary: I've now had this unit 2 weeks and am going to return. If you're always near an a/c outlet and have your power cord on-hand, then you'll enjoy this unit. Other than that, after doing much research, this is a common problem. After searching Lenovo forums I ran across a many months old heated thread about the extremely low battery life every other user is getting as well. To the point they discussed a class action lawsuit toward the end.
Summary: Great design, fast enough for what I use it for, but....touchscreen refuses to work after applying all the updates. SSD fails on the targeted read test. There is some version conflict between drivers and os, suggested updates do not resolve it. As I say, great design, I just wish it would work properly.
