At 2.3 lb., the Acer Aspire S7 is half an inch thick, has a chic aluminum case and should be a great travel companion. The system sports an 11.6-in, multi-touch screen that can show 1920 x 1080 resolution and resists wobbling when you tap on a tile or swipe your finger across the screen. Best yet, it folds all the way flat for slipping under a monitor stand. Model 191-6640, which is pictured here, comes with 4GB of RAM, a 128GB SSD and a 1.7GHz Intel Core i5 processor and sells for $1,119.99. Acer will also offer similar S7 systems with 13.3-in. displays.
