| The Bottom Line | The Asus Zenbook UX31E is an excellent-looking Windows Ultrabook laptop that matches the MacBook Air step for step with an even better price. Fans of great audio, high-resolution screens and lots of ports will be happy; keyboard/touch pad aficionados will be disappointed. | The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience. | While it's not going to dazzle anyone, the Toshiba Satellite U845T is a great example of exactly how much laptop $799 should buy in 2013. | The Asus Zenbook UX51Vz-DH71 is a nice fit for anyone looking for premium looks and performance in a Windows 8 laptop who is willing to pay for it. | With a Core i7 CPU, discrete graphics, and a full HD screen, the Asus Zenbook UX23VD is pretty close to being the ultrabook that has it all, but you'll pay for all those features. | Basic specs |
