But it's not only the body of the tablet that got an upgrade. New Surface Type Covers will work with the Surface Pro 4 and Pro 3. These are the lightest and thinnest Type Covers Microsoft has ever made, with an integrated, backlit keyboard, softer key mechanics that make them quieter, and increased travel between keys. They also have a fingerprint reader for added security and come in five colors.
Both look almost identical at first glance, with the same silver magnesium alloy bodies and 12-inch displays. But the Surface Pro 4 is actually thinner and lighter at 8.44mm and 766grams—the Surface Pro 3 is 9.1mm thick and weighs 798 grams. They have the same width so most accessories with the Surface Pro 3 are compatible with the newer version. The Type Cover of the Surface Pro 4 keyboard provides a much more comfortable typing experience, with a larger 19mm pitch and 1.3mm travel. The trackpad has been improved as it is 40 percent bigger and is made from glass. And the beautiful thing is the new keyboard is compatible with the Surface Pro 3. The newer pen has 4 times better pressure sensitivity and can also be used with the older 2-in-1 model.
