Wireless And Sensors
Here too exist substantive differences. Surface Pro 2 includes only Wi-Fi a/b/g/n and Bluetooth 4.0. To those, Dell (pictured) adds NFC as standard equipment and 3G and 4G LTE mobile broadband as options. Interestingly, Dell has opted not to include sensors for ambient light, movement, orientation and acceleration. Microsoft's device has all of these. Neither device includes a GPS receiver. Microsoft includes a stylus; Dell makes it optional.
