Like every Surface tablet, the clip-on keyboard is best-in-class. The keyboard and stylus are great, but there's a catch. On other devices, including the Surface Pro X, the pen supports the same 4,096 pressure levels as the previous model and maintains compatibility with Surface devices going back to the Surface Pro 3. The Pro X, on the other hand, offers a big screen and slim body. We’ve tested specs, ARM performance, battery life, and apps.

Microsoft has also updated the Surface Slim Pen-the $130 Slim Pen 2 moves the pen's button from the narrow side to the flat side and adds a haptic vibration motor to recreate the 'feeling you get with pen on paper.' That functionality, however, apparently requires the Microsoft G6 chip in the Surface Pro 8 and Surface Laptop Studio. Microsoft’s Surface Pro X promises great battery life in a sleek form factor, but we put it to the test against the Surface Pro 7. The Surface Pro 8 has adopted most of the Surface Pro X's design improvements, but the Surface Pro X does remain slightly thinner, is totally fanless, and is about a quarter-pound lighter (1.7 lbs compared to 1.96 lbs before you add a keyboard or other accessories). Microsoft is, however, releasing a Wi-Fi-only model that brings the tablet's entry price down to $899 (compared to $999 for the LTE base model, which also includes a Microsoft SQ1 processor, 8GB of RAM, and 128GB of storage).

Microsoft has significantly revamped and upgraded the x86-based Surface Pro and Surface Go tablets today, but the ARM-based Surface Pro X isn't getting any hardware upgrades of note.
