Pulling the 14-inch Acer TimelineX 4820T from its box, one thing went through our mind: this could be the perfect thin and light laptop. The $717 system is about an inch thick, weighs only 4.7 pounds, and still has an onboard DVD drive. And unlike the past Acer Timelines and their sissy ULV processors, it has a standard voltage Core i3-350M CPU, 4GB of RAM and a 320GB hard drive. Oh, and it promises over seven hours of battery life. Sound like the perfect no-compromise ultrathin laptop to you too, right? Well, even after our unboxing, the TimelineX 4820T did live up to many of our expectations, but disappointed in some unfortunate others. We’ll explain it all in our full review after the break.
