The Lenovo IdeaPad U410 is a very affordable Ultrabook. It will be difficult to find elsewhere an Ultrabook with a Core i7, 8 GB RAM and a 1 TB hard drive at a similar price. If you don't mind the weight, then this laptop is certainly an interesting option.
The build-quality of the chassis is not as solid or sturdy as we'd like. The hard drive is not the fastest, and we would have preferred a better display. Other drawbacks are the slow wireless and 100 Mbit network ports. In spite of that, Lenovo has created a very interesting and powerful Ultrabook for a sharp price.
The Lenovo IdeaPad U410 costs £799 and comes with a two-year warranty.
