High-performance PC gaming requires a lot of power. More power than you can fit in a typical laptop. So instead of chaining you to a desk or selling you a pizza box-sized portable, the Razer Blade Stealth lets you have both a high-end gaming PC and an ultrathin laptop, thanks to a smart, simple compromise. The Intel Core i7-powered laptop sports a 12.5-inch high-res touchscreen, yet has an aluminum chassis that measures just over half an inch thick and lets the package weigh in at under three pounds. All of this makes for a capable laptop, but when it's time to game, you use the Thunderbolt 3 port to connect to your desk-bound, sold-separately Core, which houses a double-wide, full-length PCIe graphics card from your choice of AMD or Nvidia, as well as a host of extra ports, a beefy power supply, and plenty of heat dissipation. Portability when you want it, power when you need it — the computing equivalent of a mullet.
Up 'til now, the Surface has been stuck in a weird limbo between tablet and laptop. No more. The Microsoft Surface Book is designed to be a killer laptop and a killer tablet. Its unique hinge lets you detach the screen from the keyboard, turning it into a tablet, and reattach the screen facing out, letting you take advantage of the powerful, MacBook Pro-besting processor, RAM, and graphics built into the keyboard base without giving up the highly responsive, pressure-sensitive stylus and finger-ready touch surface. You can also pair it with a Surface Dock for desktop use, but even if you don't, it's the most interesting device that we've seen out of Redmond in, well, ever.
