The Dell XPS 13 was released earlier this year and it blew everyone away. However, the company is ready to bring back a 15-inch number in the form of its XPS 15. And then there's the Microsoft Surface Book, which, according to Tech Radar marks the company's entry in the laptop arena. Said to be the thinnest Windows 10 machine ever created, the Surface Book stole the show from even the latest Surface Pro 4 model.

The 2-in-one laptop can snap off to become a 7.7mm-thick tablet and is entirely performance-focused as far as hybrid gadgets are concerned. With its NVIDIA graphics card, it can offer up to 12 hours of battery life, which is saying something. However, as it is with gadgets the XPS 15 comes with its own competition in the form of Microsoft's Surface Book.

The Surface Book has a 13.5-inch screen with a 3:2 aspect ratio, considered to be a large device as far as 2-in-1 laptops are concerned, however, its appeal stands on its hinge -- the magnesium body literally folds and expands as users open the book, and the screen portion can be pulled off the keyboard with its One-button Muscle Wire detach mechanism.

Unfortunately, it's a bit on the heavy side, weighing 3.34 pounds all in all, but the good thing about having a detachable screen means that for those on the run, the tablet portion of the gadget weighs only 1.6 pounds.

On the other hand, The Verge noted that the XPS 15 has an edge-to-edge display with 4K graphic resolution, making it a beautiful piece of gadget that emphasizes on the lack of bezels on the larger display as opposed to the XPS 13.

Like its predecessor, the XPS 15 comes with machined aluminum and carbon fiber which gives it an XPS 13 feel, but weighing very differently.

For the rest of the specifications, the XPS 15 comes with the Core i3 version of the base model, which can go up to the Core i7 for more power.

For its battery, Dell made it a bit more interesting with the regular HDD model sporting a 56W battery, but SSD models get 84W. This means that those who want a longer battery life don't get to have the 4K model, although Dell is promising great features like 10 hours of wireless web browsing for the Core i7 with 4K display, and 17 hours for the Core i7 with HD display.

For those who want to know the specs, however, Tech Radar noted that very little is known about the Surface Book at this point, and the company has not yet disclosed the exact GPU model, although it is rumored to come with 1GB of GDDR5 memory.
More news will come regarding both models soon, but as for now, which one do you like better?
