ASUS' Zenbook UX301 was already rather impressive with its glass-covered body and 2,560 x 1,440 touchscreen, but its record has just been broken by yet another Zenbook. Announced at IFA today, the new UX305 is a gorgeous all-aluminum Ultrabook that packs an insanely sharp 13.3-inch 3,200 x 1,800 (276 ppi) display (as used by the bulkier UX303LN), and at just 12.3mm thick, it's certainly the world's slimmest laptop to carry this class of screen resolution. The trade-off here is that this isn't a touchscreen, but the 1.2kg weight does beat the 1.35kg 13-inch MacBook Air. Much like the rest of the Zenbook series, the UX305 is also quite the looker with its diamond-cut highlights plus signature spun-metal finish in either "Obsidian Stone" or "Ceramic Alloy" color option. Little else about this laptop has been mentioned so far: All we know is that it'll pack an Intel Core M processor, 10 hours of battery life and a choice of 128GB/256GB SSDs. We'll get back to you guys when we hear more later this year.
