The Surface Pro 3 comes as a 3rd gen tablet from Microsoft.
It is the complete Windows 8 PC and has the same internals as the laptop. However, it has been designed as a hybrid, so that it can be used as a laptop as well as a tablet. There are certain additional features when compared to the previous version, namely Surface Pro 2.
Change in Stylus
The Pro 3 comes with an N Trig, a digitizer stylus, compared to the Wacom stylus of the Pro 2. The stylus in the Surface Pro 3, therefore, needs a battery, whereas that of the Pro 2 does not need one. The Wacom based stylus of the Surface Pro 2 also comes with higher sensitivity of 1000 plus, compared to 256 of the Pro 3. The new stylus of the Pro 3 is more accurate when used in the screen edges, whereas the Pro 2 stylus does not work very well at the corners. The stylus of the Pro 3 is, therefore, better for taking notes and for handwriting, but the pressure sensitivity of the Pro 2 stylus is more suited for digital artists.
The Surface Pro 3 comes with a larger screen than its predecessor. The Pro 3 comes with a 12. 1 inch display compared to the 10.6 inch display of the Pro 2. As it has a bigger screen, the Pro 3 can be said to be a very good replacement for a laptop. The new screens make the Pro 2 work well as a laptop and also as a tablet, as the screen in this case, is squarer.
Display and Resolution
The screen of the Pro 3 is larger than that of the Pro 2. In addition, the resolution of the Pro 3 is also improved. The Pro 2 has a 10.6 inches screen with a resolution of 1080p, which gives it a ppi of 208. On the other hand, the Pro 3 from Microsoft comes with a better resolution of 2160 x 1440, which results in a ppi of 214.5. It is only slightly sharper than the Pro 2, but the density is higher and the sharpness is not lost though it has a bigger screen display. The screen of the Pro 3 is brighter and offers better contrast as well.
Lighter and Slimmer
The Pro 3 is 800g in weight and is lighter than the Pro 2, though it is bigger. The Pro 3 is 9.1 mm in thickness compared to the 13.5 mm of the pro 2. The screen bezels are also narrower in the Pro 3. However, the Pro 3 is bigger in size, so you cannot fit it in the small tables on a flight or a train. However, the Pro 3 is a very good laptop replacement when used on a regular desk, though it cannot be a good replacement in all environments.
There are significant improvements in the speaker as well. The Pro 3 comes with speakers that are 45% louder when compared to those of the Pro 2. These can be very ideal if you are planning to watch Netflix while in bed.
The battery life of the Pro 3 is also better when compared to the Pro 2. The Pro 3 has a battery stamina that is better by about 20%. In addition, the Pro 3 is surely more powerful, though both the tablets make use of the same Haswell processor. However, the Pro 2 makes use of an Intel Core i5, 4200U chip, whereas the Surface Pro 3 has a higher Core i7 CPU. This has improved the performance of the Pro 3.
