I bought a 12" Intel I7 thinkpad yoga about a year ago and still absolutely love it. I use it for both business and personal use and travel with it often. I did upgrade mine to the higher res screen, the I7 processor, and 8 mb of ram and got it for around $1,500 on Amazon. The keyboard is fantastic to use and is my favorite keyboard of any computer so far. I just got a new Dell Latitude E7240 that might job bought me and I far prefer the Lenovo by far. If I had to get another personal laptop I wouldn't hesitate to buy this again.
By the way, with the flexibility of the 12" screen I often read books on it or watch videos. On a plane I often convert to tablet and read a book. I have 2 ipads that literally haven't been charged in weeks to months and I no longer use my iPad. Between my Samsung Galaxy S5 and this computer I no longer desire an iPad. Much recommended!
