The Galaxy TabPro S is like the iPad Pro in that it has only a USB-C port. That means if you want to charge the device, use a thumb drive and connect to a display, you're going to need an adapter. For entertainment, you probably don't need a device with so many ports, but in a business setting, ports become far more important. The TabPro S also lacks a microSD slot, which means you can't expand the storage or swap out microSD cards as needed.
Winner: If you want a lot of connectivity built into your device, the Surface Pro 4 is a clear winner, offering more flexibility and connectivity for business users.
The display size on the Galaxy Tab Pro is 12 inches, while the Surface Pro 4 display measures at 12.3-inches. The difference in size is barely noticeable. In terms of resolution, the TabPro S has a 216 ppi display, while the Surface Pro 4 resolution is 267 ppi. While it might seem the TabPro S has a lower resolution, the fact that it's a super AMOLED display puts it on par with the Surface Pro 4 IPS display. Both are gorgeous, crisp and clear and you can't go wrong with either display. The Surface Pro 4 does have better integrated graphics in the i5 and i7 models, but the TabPro S and entry level Surface Pro 4 share the same Intel HD 515 graphics card.
Winner: Although Samsung offers the first SuperAMOLED display for Windows tablets, both devices offer a clear and flawless display. This one is a tie as you won't miss out on a stunning display with either device.
The biggest accessory with any hybrid is the keyboard, but it gets a bit tricky when comparing the Surface Pro 4 keyboard and the Samsung TabPro S keyboard. Both companies got a lot of things right, but they also got a few things wrong. Let's start with the Surface Pro 4 keyboard. It magnetically attaches to the base of the tablet and it doesn't support the device -- you'll use the kickstand for that instead. It's comfortable to use regularly, and the trackpad is responsive. The downside comes when you realize you have to purchase the keyboard separately, which raises the price of the device by at least $115, if you can find the keyboard on sale. Plus, the lack of stability makes it a bit wobbly in your lap, and you have to be careful when you pick the device up since it is so top heavy.
Samsung includes its keyboard stand in the price of the device, and it's more like the iPad Pro keyboard in how it supports the device, but it's also firm and sturdy, which gives the device a more solid base. However, you get only one good viewing angle, and the second viewing angle is awkward and seems impractical for daily use. That might get frustrating fast, especially if you're trying to use the device anywhere other than a desk.
