Not to be outdone by HPs latest super-slim offering, Acer has released its Timeline series. These 13.3in. 14in, and 15.6in laptops are less than an inch thick, but still pack some pretty decent tech. They squeeze out 8 hours of battery life, thanks to LED backlit screens and ultra-low voltage processors, with support for a 64GB SSD drive too. And they sit around the US$700 mark, which sounds pretty good to us.
