I'm the opposite, I value typing economics above all else, and I'd much rather have more battery life than save a little on weight. For me, 14" is the perfect screen size because it gives me a decent sized keyboard, enough screen to see what I'm doing, it's small enough to fit in my backpack, and large enough to fit a large enough battery to last all day. But for some reason the most recent Thinkpads don't offer a second battery and are trying to go thinner, which is precisely what I don't want. I have my desktop for serious typing and my laptop for a mobile workstation. Sometimes I need to work while visiting family or when going to conferences, and I need a decent keyboard, battery, and performance to do so. If I want thin, I'll get something like a MBA, a tablet, or my little Lenovo Yoga (11"). But that's not enough for me to get work done on the go, it's mostly just barely good enough to take notes and watch videos. I need something capable of compiling decently large codebases and 3D rendering, and no MBA is good enough for that.
