After I received my M4 iPad Pro 13" iPad Pro I thought I'd dress things up a bit. I found a very nice leather briefcase, at a reasonable price, from Blackbrook. Even though it was discontinued product and non-returnable I took a chance and ordered it. I plan to use it for day trips like visiting a coffee shop.
Today I received it and I can say it is a high quality case if you want something minimal and a bit dressy looking for your iPad or up to 14" laptop (according to their website).
There is one tablet/laptop compartment inside and a couple of other small pockets. There is no padding. So be forewarned about dropping the briefcase with your device in it. Though I do plan to add a Zugu case when released, and already have a Magic Keyboard, which might help a bit if the briefcase were dropped. This is just speculation on my part.
Also, I'm pretty sure it is not water resistant due to its leather construction.
