Ultimately this laptop has achieved everything I would hope for in a laptop for work, while fitting that into a form factor and weight that is remarkable.
This smart laptop was enjoyable to use and great to work on — creating content was super simple. As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess sports mode if you will in between.
This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web. Join the newsletter! Sign in with LinkedIn Sign in with Facebook.

If you want increased screen contrast and clarity, capacitive touch screens are the preferred option over resistive screens, which have more reflections due to their number of layers. However, because of these advantages, they are sometimes less cost-effective than resistive touch panels.
Although capacitive touchscreen technology was invented long before resistive touchscreens, capacitive technology has seen more rapid evolution in recent years. Thanks to consumer electronics, particularly mobile technology, capacitive touchscreens are swiftly improving in both performance and cost.
At GTK, we find ourselves recommending capacitive touchscreens more regularly than resitive ones. Our customers almost always find capacitive touchscreens more pleasant to work with and appreciate the vibrancy of image that cap touch TFTs can produce.
With constant advancements in capacitive sensors, including new fine-tuned sensors that work with heavy duty gloves, if we had to pick just one, it would be the capacitive touchscreen. Sensors positioned under the screen sense the change in voltage, and the location of that change. In a device that uses a projected capacitive setup, transparent electrodes are placed along the protective glass coating in a matrix formation. One line of electrodes vertical maintain a constant level of current when the screen isn't in use.
Another line horizontal are triggered when your finger touches the screen and initiates current flow in that area of the screen. The matrix formation creates an electrostatic field where the two lines intersect. This is one of the most sensitive types of touchscreens, and is how some phones can sense a finger touch even before you make contact with the screen itself.
Projected capacitive technology also allows you to use the touchscreen even when you're wearing thin gloves. The choice to use a capacitive or resistive touchscreen depends largely on the application for the device. Most devices with resistive screens are used in manufacturing, ATMs and kiosks, and medical devices.
This is because in most industries the users need to wear gloves when using the touchscreens. Capacitive screens are typically used in most consumer products like tablets, laptops, and smartphones. If it weren't for cutting edge touchscreen technologies, we could never enjoy cool new applications like Opera's one-handed browsing for Android. The applications are only going to expand as the technology continues to be refined. Cramming for a geography exam? These iPhone apps make it fun to study geography.
