It also has a magnetic strip which binds to the front bezel of the display for additional stability. The magnetic strip can also be used to elevate the position of the keyboard, which can help to comfortably use a Type Cover on a lap. The Surface Pro 3 is the first Surface device to feature an improved version of the Surface Pen, which is included with each device. In contrast to that from the earlier devices of the Pro line, which was based on Wacom technology, the Surface Pen of the Surface Pro 3 features N-trig DuoSense technology with 256 levels of pressure sensitivity. Microsoft also offers a docking station, which adds five USB ports (including three USB 3.0), a Gigabit Ethernet port, an additional Mini DisplayPort (which can be used simultaneously with the port on the Surface Pro 3) and a 3.5 mm audio socket for audio input/output. Some of Microsoft's wireless touch mice were restyled to match the Surface-series devices design, added where applicable a Bluetooth connectivity and relaunched as "Surface Edition" series mice: Arc Touch Mouse Surface Edition and Wedge Touch Mouse Surface Edition. The Surface Pro 3 has received positive reviews. David Pogue suggested "The upshot is that, with hardly any thickness or weight penalty, the kickstand and the Type Cover let you transform your 1.8-pound tablet into an actual, fast, luxury laptop". Pogue said that the Surface Pro 3's form factor works well as a tablet, in contrast to the Surface Pro 2, whose bulk and weight limited its appeal as a tablet. Pogue also stated that the new multi-stage kickstand, 3:2 screen aspect ratio, and new Type Cover 3 detachable keyboard made it a competent laptop. It has been suggested that the Surface Pro 3 comes closest to the Microsoft Tablet PC concept that company founder Bill Gates announced in 2001, being the first Surface to become a credible laptop replacement. "Time" magazine included Microsoft Surface Pro 3 in the list of the 25 best inventions of 2014. The Surface Pro 3 received a repairability score of 1/10 from iFixit because of the use of a strong adhesive material throughout and the difficulty in removing the display.
