Ultrabooks are a wonderful thing, but they're known to require compromise: you get this (usually thin and lightweight construction), but you have to sacrifice that (let's say battery life and durability). It's this very nature of compromise that turns many off; more than a few laptop owners have gone with larger, heavier models to get the things their ultrabook counterparts couldn't offer. Lenovo's ThinkPad X1 Yoga ultrabook changes this -- there is no compromise needed. In fact, you'd be hard-pressed to find any laptop, ultrabook or otherwise, that can stand up to the utter gem that is this Yoga model. I don't ordinarily feel like reviewing something is an honor, but the ThinkPad X1 Yoga is no ordinary ultrabook.
