Dell Precision M4600 compare

The newly redesigned MacBook Pro with Retina Display combines an amazing screen with just enough of the MacBook Air design to feel like a new animal, and to take its place as the best of the current MacBook breed.

The Lenovo IdeaPad Yoga 13 is a convertible touch-screen laptop/tablet that most importantly doesn't compromise the traditional laptop experience.

For those looking for something more than a feature-light ultrabook, the gamer-friendly Lenovo IdeaPad Y500 is close to brilliant, and several configurations are currently available at a deep discount -- but I can't believe it doesn't have a touch screen.

If you've got the money--and a strong back--the Dell Precision M4600 is a very good mobile workstation.

A total revamp of Dell's ubiquitous business laptop line, the Latitude E6400 offers Intel's latest Centrino 2 mobile platform and introduces a brushed-metal design that works at home or office, but the real highlight here is the long battery life.
