Pretty much since the original Surface was born, I, and many others, have wished that Microsoft would try their hands at a laptop computer. It’s not even that the original Surface was a great device, but the whole idea was to kickstart some new device types, and now Surface has turned into a big business in its own right. The latest Surface Pro 4 looks to be the best iteration yet.

So today Microsoft is trying to redefine the laptop category with the Surface Book. With Surface Pro, it was the tablet that can replace your laptop, and with Surface Book, it is what Microsoft is calling “The Ultimate Laptop” and we shall see about that but it has a lot going for it. Compared to the Surface Pro 4, the display is larger at 13.5-inches but keeps the same 3:2 aspect ratio that has now defined the Surface lineup. People sick of 16:9 laptops should be happy to see this.

The display itself is 3000x2000 pixels, which works out to exactly 6,000,000 pixels and the same 267 pixels per inch of the Surface Pro 4. It has the same 0.4 mm thick Gorilla Glass covering as well, and contains the same PixelSense capabilities that mean it will also work with the pen and of course touch. Each panel is calibrated for sRGB out of the box.

This is not your ordinary laptop where the display is just the display and the key components of the notebook are under the keys. Instead, the screen is detachable like many two-in-one devices, but the base itself is connected and houses the NVIDIA GPU and some batteries, as well as USB ports and a SD card reader like you would expect on an Ultrabook.

The hinge is certainly very interesting, and it kind of reminds me of a new take on the Yoga 3 Pro’s keyboard hinge, although this one is much thicker. Microsoft calls it a Dynamic Fulcrum Hinge. One weird thing about the hinge is that when the device is closed, the top and bottom don’t meet. It is weird to see but I would need some more time with it to see if it is an issue. A benefit of the slightly raised rear is when the display is connected flipped around for writing, the glass is slightly tilted towards you which is something I often find myself doing with the Surface lineup of tablets.

The latching system is ridiculously strong. Microsoft is using a wire that can change its length if a voltage is applied to it. You have to press and hold a button on the keyboard to invoke this charge so the actual separation is never going to be by accident, but it does take longer than some other detachable devices.

I am a bit of a keyboard nut myself, and I really like a proper keyboard, so it is great to see that the Surface Book will have 1.6 mm of key travel, and a nice layout. I am generally not a fan of light keys with backlighting so we will have to see how this holds up in the real world. The trackpad is a Microsoft Precision trackpad with a glass top and five points of touch.

On the spec side, there will be Core i5 and i7 versions of this available, and the GPU is optional with the Core i5, but standard with the Core i7. Base configurations come with 8 GB of memory, but there is a 16 GB version as well, and storage is PCIe based SSDs from 128 GB to 1 TB.

Size and weight are always a key with this class of device, and despite the 13.5-inch size, the tablet itself only comes in at 1.6 lbs or 726 grams. Adding the keyboard moves the Surface Book out past the incredible weight of some of the latest Ultrabooks, with the non-GPU version coming in at 3.34 lbs or 1.51 kg, and the GPU adds a bit more weight to come in at 3.48 lbs or 1.58 kg.

The Surface Book will go on pre-order tomorrow starting at $1499 up to $2699 for the Core i7 with 16 GB of RAM and the GPU. No 1 TB models are listed yet but they were announced. Microsoft is likely waiting on manufacturers to offer M.2 1 TB models.

    Hm, I had assumed it would use the ultrabook dual core i7s, and the double the performance meant on the GPU side. If they meant processors it could be quad though.
  • IanHagen - Tuesday, October 6, 2015 - link

    Agreed. I'd like to see some numbers backing that up. Skylake isn't twice as fast compared to the rMBP 13 Broadwell nor is it's GPU. Maybe they're claiming that the dedicated nVidia GPU card ($1899 offering) will be twice as fast as the base rMBP 13 Iris 6100 ($1799 offering)...

    They were probably referring the the MacBook Pro Apple sold three years ago...
  • nerd1 - Tuesday, October 6, 2015 - link

    That's almost a lie. The CPU itself is 15Watts compared to 28 Watts one in rMBP 13", and discrete GPU is optional.
  • Morawka - Tuesday, October 6, 2015 - link

    i'm guessing it's still faster even with the different tdp because of the new architecture and EDRAM
  • nerd1 - Tuesday, October 6, 2015 - link

    CPU performance is limited much more by thermals than generations, and you won't get a good thermals with 7.7mm thin case.

    This is what he said, word for word:

    "By adding the discrete GPU, two extra processors, it fundamentally makes surface book two times faster than a MacBook pro."

    It's still quite vague. Take from it what you will. I'm going to wait for more detailed specs, exact GPU and CPU models, clock speeds, etc.
  • tipoo - Tuesday, October 6, 2015 - link

    Hmm. i wonder if GPU upgrades could be in the future since they're in the keyboard part.

    Also wonder how close the Skylake Iris with 64MB eDRAM comes to the old Iris Pro 5200 with 128MB. Intel did say 128MB was very overprovisioned and they really only needed 32, so it could be close.

    If it is close, one may not even miss the ambiguous Nvidia GPU.
  • IanHagen - Tuesday, October 6, 2015 - link

    Which model comes with eDRAM? Isn't HD 520 supposed to be the non-eDRAM version?
  • Morawka - Tuesday, October 6, 2015 - link

    in the slides they showed EDRAM i5 with PCH onboard.
