Featuring a slim-and-light design, silver aluminium unibody casing and black chiclet-style keyboard, there's no prizes for guessing who Chillblast is trying to appeal to with its 14-inch Helios ultrabook. All that's missing is a black fruity logo.At £700 (around US$1,098, or AUS$1,501) it's around £150 (around $253 or AUS$321) cheaper than Apple's entry-level 13-inch MacBook Air while offering a higher-resolution display and a faster Intel Core-i5 processor.It's around a third cheaper than Dell's entry-level XPS 13, which packs an impressive practically borderless Infinity Display, but it's slightly more expensive than Asus's impressive Core M-powered ZenBook UX305.DesignWindows ultrabooks that ape the MacBook Air's design usually fall into two camps: those that do so subtly and others that don't try to hide it. The Helios falls in the latter, and just like the Air you'll either find its minimal style bland or elegant depending on your taste.There's an indent at the front of the base unit which makes it easier to raise the lid, but we noticed that the lid's rim can feel quite sharp to the touch as there is a slight overlap on the display.In all other respects, both the casing and the hinge feel sturdy and secure ? there's no noticeable flex during handling.
