Acer just ‘launched’ (how many launches does it take to get a device to market these days!) the Acer S5 Ultrabook in the UAE. The 15mm thick Ultrabook with the cool Magic Flip motorized port panel is said to be the thinnest yet. The 1.3KG (under 3lb) Ultrabook will cost, at launch in Dubai, Dh4,999. We assume that’s a zero sales-tax price which equates to $1361 at todays rates.
