Funny as it may sound, the Razer Blade might fit that bill for you, depending on what you mean by &#x27;ultrabook&#x27;.<p>It&#x27;s a 14&quot; Retina-like notebook, great trackpad with click buttons, extremely powerful internals, all-metal chassis, and only slightly bigger than a Macbook.  They sell them at the MS store and if you buy from there they come with plain-vanilla Windows installed, without crapware.  They also run Ubuntu extremely well.<p>There are downsides: it&#x27;s very expensive, you&#x27;re buying from a less-well-known supplier, parts are proprietary so home repair is out of the question, and you have to be OK with the black chassis and 90&#x27;s-hacker-green keyboard.<p>But the system itself is outstanding.  Don&#x27;t know why it&#x27;s not recommended more often, especially considering it&#x27;s very Linux-friendly.
