Dell's eagerly-awaited Adamo XPS, which many are calling its rival to Apple's Macbook Air, has a rather novel opening system. There's a heat-sensitive strip across the front of the device that you swipe a (warm) finger across to unlock the mechanism and allow you access.

It's clear that this is just a novelty - has anyone ever had any issues with laptops accidentally opening in their bag? - but it's a pretty nifty novelty nonetheless, in keeping with the "luxury" design of the series that Dell's trying to convey.

The super-slim machine hasn't been issued with a release date or price yet, but we're pretty sure it's not going to be cheap.
