Microsoft has been busy rounding out its Surface line, most recently with new Surface Pro, successor to the well-received Surface Pro 4. Here's how the specs and features of the new 2-in-1 tablet compare to those of its big brother, the Surface Book.

To start with, these two machines have slightly different 2-in-1 form factors. The Surface Pro is a tablet first. It can be used with or without its Type Cover keyboard accessory, which is sold separately.
The Surface Book is also a tablet with a detachable, reposition-able keyboard, but for the most part, the tablet and keyboard are meant to be used together, though you can occasionally use it as a (huge) standalone tablet if you'd like.
The Surface Book is a larger device overall, but keep in mind that these measurements are for the Surface Pro tablet only. The keyboard is included in the Surface Book measurements.
When the Surface Book is closed, its hinge creates a gap and a tapered profile when viewed from the side. Also, the Performance Base edition – which is the more souped-up model –starts off a little thicker. It's 15 mm at its thinnest point.
The Surface Book is also heavier, but again, the weights shown for the Surface Pro are for the tablet only (the Signature Type Cover accessory adds another 0.31 kg).
Microsoft uses a magnesium alloy for the outer build.
The smaller Surface Pro offers 83-percent of the overall display area of the Surface Book. Both have 3:2 aspect ratios.
As tablets (or semi-tablets) both machines have touchscreen displays.
They also have high display resolution with matching pixel densities.
Neither device has a built-in fingerprint sensor. Some of the older Type Cover accessories have fingerprint sensors, however, and at this point they appear to be forward-compatible.
You're not out of luck when it comes to biometrics. Both devices support the facial recognition feature in Windows Hello for fast and secure log-ins with just a flash of your mug.
Both devices support the Surface Pen stylus. It's bundled with the Surface Book, but with the new Surface Pro, you'll have to buy it separately for US$99.
The Surface Pro has new and improved 7th-generation Intel Core processors, but its entry-level m3 chip is relatively weak compared to the more capable i5 and i7 tiers.
The Surface Pro offers only embedded graphics, but with the Surface Book, you can upgrade to NVIDIA GeForce graphics.
The entry-level Surface Pro starts off with a fairly paltry 4 GB of RAM, but the i5 and i7 models start off with 8 GB. With either device, you can also upgrade to 16 GB of memory.
There are four storage capacities available, starting at 128 GB and maxing out at 1 TB.
If a quiet machine is a priority, go for the Surface Pro with an m3 or i5 processor, which are both fanless.
Both machines stick with legacy USB 3.0 ports – one on the Surface Pro and two on the Surface Book. There's also a mini DisplayPort on each.
Both tote a pair of stereo speakers with Dolby Audio Premium.
By Microsoft's estimate, the entry-level Surface Pro should get more battery life than its Book counterpart, but it's important to note that battery life estimates for the Surface Book are based on using the tablet with the keyboard attached. The battery is actually split between the keyboard and the display, with the majority being in the keyboard. If you use the tablet alone, battery life drops to just a few hours.
Like most tablets, this pair has both rear-facing and front (selfie) cameras.
They also both run Windows 10.
The Surface Book made its first appearance in October of 2015; the more powerful Performance Base model was introduced in October of last year. The recently refreshed Surface Pro is available for pre-order now to start shipping in June.
The entry-level Surface Pro is more affordable than the Surface Book, but it's certainly possible to catch up in price once you consider accessories and upgrades. A Signature Type Cover costs $160, and it's $99 for the Surface Pen stylus.
Some potential advantages of the new Surface Pro include portability, newer processors and lower price. But on the other hand, all of the accessories are included with the Surface Book, plus it has a larger display and upgradable graphics.
