Best Keyboard Case for Surface Pro 11 and Surface Pro 9: Dexnor Backlit Trackpad Folio, $119.69

The Laptop That Unfolded Its Own Keyboard

In 1995 IBM shipped a subnotebook that did a magic trick. The ThinkPad 701C had a 10-inch body but a full-size keyboard, and the way it managed that was pure mechanical theater: open the lid, and the keyboard split diagonally into two halves that slid apart on a hinge and locked together wider than the computer itself. IBM called it TrackWrite. Everyone else called it the Butterfly. It was so well executed that a 701C sits in the Museum of Modern Art's design collection to this day.

The Butterfly died within two years, killed by the one thing nobody predicted: screens got bigger. Once laptops had 12-inch displays, the chassis was already wide enough for a full keyboard and the trick was pointless. But the problem it solved never went away. We just moved it. Today the small-body, full-keyboard problem belongs to tablets — and the answer is a detachable keyboard folio instead of a folding hinge.

The Dexnor Surface Pro 11 / Pro 9 Case, in Detail

The headline item here is the Dexnor backlit keyboard folio for Microsoft Surface Pro, listed at $119.69 (down from $125.99). It is a folding folio in black, and it covers the two things thin travel keyboards usually skimp on: it has a backlight and it has a trackpad. Connection is Bluetooth, the case is magnetic, and the tablet holder rotates, so the same case gives you a laptop posture, a raised stand posture for video, and a flat tablet posture for reading or pen work.

That rotating hinge is the part people underestimate. A fixed folio forces you to unclip the tablet every time you want to sketch or read, and the case you unclipped ends up on the floor of a coffee shop. A rotating mount means one object, three shapes.

Bluetooth vs. Pogo-Pin: the Thing to Check First

Tablet keyboards attach in one of two ways, and it decides how the thing lives with you.

• Pogo-pin / Smart Connector. Magnetic contacts on the tablet feed power and data straight through. No pairing, no charging the keyboard, no battery to die. The catch: it only works on the exact tablet generation the connector was designed for, and if the tablet drops the connection you have no fallback.
• Bluetooth. The keyboard has its own battery and pairs like any other accessory. That means it needs charging every few weeks — but it also means it will talk to a phone, a second tablet, or a desktop, and it isn't locked to one port design. For anyone who owns more than one device, that flexibility usually wins.

Backlighting is almost always a Bluetooth feature for the simple reason that lighting keys costs real power. If you type on a plane, in a truck cab, or in a bedroom with someone asleep next to you, that's the whole decision.

Why the Trackpad Matters More Than the Keys

Most people shop these cases on key feel and then never notice key feel again after a week. What they notice every single hour is the trackpad. Without one, every menu, every cell in a spreadsheet, every close button means lifting a hand off the keys and smudging the screen — and on a 13-inch tablet propped at arm's length, reaching the top of the display is genuinely uncomfortable. A trackpad keeps your hands home. Buy the trackpad model; you will not regret the extra inch of thickness.

If You Have an iPad or a Galaxy Tab Instead

The same case shelf covers the other big tablet families, and several are priced well under the Surface folio:

• ESR Rebound 360 keyboard case, iPad Air 13-inch M2/M3/M4 — $80.99 — rotating stand, magnetic attachment, black.
• JUQITECH backlit trackpad keyboard case, Galaxy Tab S7 / S8 11-inch — $51.19 — synthetic leather, integrated stand, with a pencil holder (MPN X00438IA53).
• Backlit keyboard case plus wireless mouse, Lenovo Idea Tab / Xiaoxin Pad Pro 12.7 — $38.49 — the only one here that ships a mouse in the box.
• typecase Touch 360 keyboard case with trackpad, iPad Pro 13 M4 / Air 13 — $35.99 — model KB201T-129, also fits the 12.9-inch iPad Pro 3rd–6th gen, one-year manufacturer warranty.
• ESR Ascend backlit keyboard case with trackpad, iPad Pro 13-inch M4 — $32.50 — down from $64.99, integrated stand, two-year manufacturer warranty.
• Sahara Navigation keyboard case with trackpad, Galaxy Tab S9 / S9 FE / S10 FE — $27.59 — synthetic leather with a pencil holder, MPN TB00329.

Three Things to Check Before You Order

• Match the generation, not just the family. "iPad Pro 13" and "iPad Pro 12.9" sound interchangeable and are not — camera bumps and magnet positions moved. Read the compatible-model line on the listing and compare it to the model number on the back of your tablet.
• Weigh the stack. A 13-inch tablet in a keyboard folio lands in real laptop territory. If the point of the tablet was that it's light, a slim non-backlit folio may serve you better than a full aluminum-feeling case.
• Decide about the pencil. If you use a stylus, a case with a dedicated pencil holder is the difference between always having it and never finding it.
