Zagg launched a version of the Pro Keys with Trackpad that’s compatible with Apple’s largest iPad. It combines a rigid, protective case with a removable keyboard with a built-in trackpad.

There were already versions of the keyboard case for smaller iPad models, and now there’s one for the 12.9-inch iPad Pro.

Apple received a patent for a foldable iPad cover/stand capable of holding the tablet up in a range of viewing angles. It’s a notable improvement over the current Apple Smart Cover.

Of course, there are plenty of third-party folding iPad stands with comparable capabilities. But people are more likely to pick Apple’s version because it’s Apple.

The Brydge 11 Max+ is a clip-on keyboard designed to make an 11-inch iPad Pro into a very portable clamshell notebook. It magnetically attaches to the tablet and adds a backlit keyboard and trackpad.

After being announced earlier this year, the product is now available in stores starting Wednesday.

While the Apple Magic Keyboard is an outstanding way to transform an iPad Pro into laptop, it’s not necessarily the best option. The Brydge 12.9 Max+ is also a very capable keyboard case for Apple’s premier tablet. I use both and pitted them against each other. And I found definite advantages to Brydge’s offering.

Slip an 11-inch iPad Pro into the newly announced Brydge 11 Max+ to convert it into a premium laptop. There’s a backlit keyboard, sizable trackpad and a clamshell design. The tablet is protected, but is held in with magnets so it’s easily removable.

The keyboard case is also compatible with the iPad Air 4. This is the second such peripheral Brydge has released for these two devices in recent months.

Logitech’s Combo Touch keyboard case just launched for iPad Air 4. It includes a detachable keyboard and trackpad, as well as a protective case with kickstand. And Bluetooth is unnecessary.

There are versions for other iPad models out already. And there is a new color option for these.

Zagg Pro Keys wraps a range of iPad models in a very protective case, and includes a removable keyboard that makes the tablet even more productive. It’s a full-featured accessory that comes at a relatively low cost.

I used the Pro Keys with my work/personal iPad for several days. Here’s what I found out.

The Logitech Combo Touch combines an iPad Pro case with a kickstand and removable keyboard. It sets itself apart from the crowd with a large trackpad and using the Smart Connector rather than Bluetooth.

I brought this keyboard case into my daily work life for most of a week. I also compared it to the Apple Magic Keyboard. Here’s why I like it.

The Zagg Pro Keys with Trackpad isn’t just for pro-grade iPad users because anyone might want the option to turn their tablet into a laptop. The new keyboard case is compatible with the 11-inch iPad Pro, the 10.9-inch iPad Air and the 10.2-inch iPad.

Zagg also introduced on Wednesday a version of Pro Keys without a trackpad for the 12.9-inch iPad Pro. And the accessory maker launched a Rugged Book keyboard case for the 11-inch iPad Pro and the 10.9-inch iPad Air.

The new Brydge Air Max+ wraps the iPad Air 4 or 11-inch iPad Pro in a protective case, and adds a removable keyboard and trackpad.

It’s a larger version of a keyboard case Brydge recently introduced for the basic iPad. And there’s a similar model for the largest iPad Pro.
