The Latitude's pin-sharp screen hit an excellent maximum brightness level of 351cd/m2, and the contrast ratio of 998:1 is superb. Our review unit ran Windows 7, so it didn't have a touchscreen.

This material is common in portable products like smartphones and tablets, so the extra protection on the laptop is welcome. Our sample was the most expensive E7440, so it shipped with a 14in 1,920 x 1,080 panel made from Corning Gorilla Glass.
We clocked a lifespan of 6hrs 43mins in our Iron Man test - over three hours less than the class-leading MacBook Air, but reasonable for a Windows device. One of the few disappointing features of the Latitude was the battery life. If you need connectivity on the move you can slot in a SIM card and use mobile broadband.

It's packing a dual-band 802.11 Wi-Fi chip, which supports the new AC standard, there's Bluetooth 4.0 and Gigabit Ethernet. The connectivity on the Dell is beaten by few Ultrabooks, if any.

Sequential read and write speeds of 477MB/sec and 396MB/sec are quicker than any hard disk, and the Latitude booted in 14 seconds - the fastest time you'll see for a Windows 7 machine. There's 8GB of RAM, and the 256GB SSD is reasonable chunk of storage. Results of 53 and 46 in the video and 3D rendering benchmarks were poor and mean it isn't the right machine if your primary needs are related to graphics. The weak graphics core brought down the overall score. The Latitude's iTunes and Photoshop scores of 85 and 95 were excellent, and the SSD's added responsiveness led to decent Explorer and app switching scores of 87 and 86. The device comfortably beat its Windows rivals and was narrowly bested by the 13in MacBook Pro. However, this still didn't stop the Latitude from scoring a respectable result of 75/100 in our benchmarks. The processor has got two cores instead of four, and it's lacking in the graphics department with the basic HD Graphics 4400 integrated. The U' suffix indicates this is a low-power part and it means compromises. It's also got vPro - allowing for remote management. The cores have Hyper-Threading, and it's got 4MB of 元 cache 1MB more than equivalent Core i5s. You've got a basic clock speed of 2.1GHz clock, which rises to 3.3GHz when Turbo Boost technology is deployed. Many Ultrabooks make do with mediocre processors, but the Latitude is powered by a top-end Core i7-4600U.

At 1.63kg and with a 21mm thickness, it's chunkier and heavier than MacBook Pro (18mm, 1.57kg). If there's a downside to the Latitude's design, it's the bulk. The Dell is the strongest laptop we've aside from Apple's MacBook range, which is crafted from one piece of aluminium. You can't flex the base or wrist-rest and the lid barely moves when tugged and twisted with no on-screen distortion.
The back of the hinge is brushed aluminium, and the Latitude has clean lines and simple curves.ĭell says this laptop is built with an underlying "tri-metal chassis", and we've no reason to doubt those claims as there's no give anywhere. We like the metallic lid, powder-coated aluminium base and the soft touch plastic used for the wrist-rest. In the middle of the keyboard is a trackpoint, which has its own trio of buttons in between the keyboard and the trackpad a feature associated with Lenovo ThinkPad laptops. The wrist-rest also has a fingerprint reader. The base has a connection for a docking station and a keyboard drainage hole. Added to this you've got a Kensington lock connector, SD and smart card readers as well as the trusty headphone jack.īusiness touches are noticeable throughout. There's a total of 3 x USB 3 ports, a mini-DisplayPort, full-size HDMI and a Gigabit Ethernet connection. It's kitted out with plenty of ports, most of which are on the rear of the device. The Latitude E7440 isn't the most glamorous looking laptop but it is functional.
The Latitude E7440 aims to tempt users with a Haswell-based Core i7 processor, 256GB SSD, good screen and some of the best connectivity we've seen on a laptop. Ultrabooks are expensive but their light and slim chassis often house powerful components which would be useful to a business user.
