Bottom Line

The Latitude E6420 is a well built business machine with good performance. However, it could use a few more standard features for the price (such as USB 3.0) and we also wish that Dell supplied both the 32-bit and 64-bit Windows 7 versions in the recovery image.

Would you buy this?

The Dell Latitude E6420 is a commercial laptop with strong build quality and good user comfort. It's a 14in model, which we think offers a good mix of user friendliness and mobility, however, at 2.4kg it is a little on the heavy side. The specific model we reviewed wasn't stacked with features — it was just the standard model. As is the case with most Dell products though, the E6420's configuration can be customised at the time of purchase.

Build quality and user comfort

The Latitude E6420 is designed to meet military standards when it comes to durability, but it's definitely not a fully rugged laptop. It should withstand some accidental bumps and spills, but you won't want to mistreat it completely. Its lid is made of anodised aluminium, while the chassis is made from magnesium alloy and the lid's latch is made from zinc alloy. Furthermore, its keyboard is spill resistant. Dell also claims that there is a protective LCD seal, which forms when the lid is closed, but we're not so sure about that — a gap is clearly visible between the lid and chassis when the lid is closed.

It definitely feels sturdily built though and it's also quite comfortable to use. Its palm rest feels soft and it isn't glossy, so it doesn't get slippery. Its keyboard has soft keys with good responsiveness and it's a pleasure to type on. The model we tested didn't have a backlit keyboard, nor a screen-mounted keyboard light, but there is an option for a backlit keyboard (an extra $37.40).

The touchpad and its buttons feel soft and the touchpad was responsive to most gestures (although three-finger flicking took a few goes before it was recognised) and there is also a TrackPoint-style device installed. This sometimes got in the way while typing.

We like the inclusion of dedicated shortcut volume buttons, which are located just to the right of the keyboard and there is a physical Wi-Fi switch on the right side of the chassis, too. We're fans of the unit's understated LED status lights — they won't be distracting while you use the notebook at night.

The 14in screen has a matte (anti-glare) finish and a native resolution of 1600x900 pixels. It's very bright and we found it to be adequate for video and photo viewing. Its vertical angles aren't great, but that's the case with almost every laptop on the Australian market. The wide screen allows you to line up two documents side by side easily using Windows 7's Aero Snap feature, which is great when multitasking. The standard model that we reviewed didn't have a webcam installed, but one can be added for $27.50.

Specifications and performance

Running an Intel Second Generation Core i5-2520M CPU with a frequency of 2.5GHz, two cores and Hyper-Threading, the E6420 is no slouch (you can also select up to a Core i7-2720QM). It also features 4GB of DDR3 SDRAM, a 7200rpm hard drive and integrated Intel HD 3000 graphics. With this configuration, it produced solid scores in our performance tests. It recorded a time of only 39sec in our Blender 3D rendering test, which is one second faster than the time recorded by the Toshiba Portege R830, for example, which uses the same CPU. It recorded 52sec in the iTunes MP3 encoding test and 52min in our DVD transcoding test and these were expected results.

Basically, the Latitude E6420 is more than capable of handling typical office applications; it's powerful enough to be used for tougher tasks such as media encoding and video rendering and it's great for multitasking. Considering it's a commercial laptop, it's also quite strong in the graphics department. It only relies on the graphics processor that's integrated in the Intel CPU, but it recorded a respectable 4486 in 3DMark06. The integrated graphics are also meant to keep the laptop's power usage in check. In our rundown test, in which we disable power management, enable Wi-Fi, maximise screen brightness and loop an Xvid-encoded video file, the laptop's 6-cell (60 Watt-hour) battery lasted 3hr 31min.

It's a decent result, but it's nothing to get excited about. The Toshiba Tecra R850, for example, which uses the same CPU and also has a 6-cell battery (albeit with a slightly higher 66 Watt-hour rating), but which has a dedicated graphics card and a 15.6in screen, recorded a time of 4hr 15min in the same test.

Around the edges, the Latitude E6420 has a decent helping of ports and slots. You get HDMI and VGA for video, Gigabit Ethernet for networking (there is also dual-band 802.11n Wi-Fi), a headphone/microphone combo port, four USB 2.0 ports (one which doubles as an eSATA port), an SD card reader and an ExpressCard/54 slot. Even though it's a commercial laptop, we're disappointed that it doesn't come with a USB 3.0 controller by default, and we weren't able to add this as an option when configuring the unit either.

Security equipment on the standard Latitiude E6420 includes a Smartcard reader and a TPM, and Computrace is supported in the BIOS. A fingerprint reader can be added for $13.20. We wish this was standard as well, especially considering that some sub-$2000 business models, such as the Toshiba Tecra E850 and even Dell's own Latitude E5520 are supplied with fingerprint readers. However, the Latitude E6420 is in a different class to those notebooks, primarily because of its construction materials, and that's why it costs more and comes with less.


Overall, the Dell Latitude E6420 is a comfortable unit to use and we like it. It feels sturdy and it also has understated good looks. We'd spec it up a little though and add a fingerprint reader as well as backlit keyboard; we're disappointed that there's no option for USB 3.0. Another quibble is that Dell makes you select from either the 32-bit or 64-bit versions of Windows 7 Professional — it doesn't supply both. Ours came with the 32-bit version as standard and when we restored the unit, it didn't give us the option of choosing the 64-bit version. Incidentally, it's a very quick recovery process — it took less than 10 minutes to reinstate the factory image.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
