Summary: This is my second X1 Carbon. I have the newer (3rd generation) model as well. The keyboard layout is a bit unusual on this model and it is occasionally frustrating. However, once you get used to it, there isn't much to complain about. Especially, given the pricing of the second generation X1's, I think it is a great value. I have had several Lenovo devices and I am very happy I purchased both versions of the X1 Carbon.
Summary: The computer is fast, amazing screen and easy to type on. It runs Adobe photoshop extremely fast. I had a question (couldn't find the serial number) and called Laptop Authority. Fast fast answering and a good answer (not a lot of stupid questions to go through before they realized I knew what I was doing). Would buy from them again.
