I travel a lot with my Macbook Pro 15 and iPad Pro 12.9 with Luna (of course!).
I researched some external portable external display for my Macbook and it still circles back to iPadPro. However, it is too expensive and could be a lot lighter and bigger.
You should create your own line of portable displays that “doesn’t suck”.
- 15 inch 4k display wrapped in custom iPad like enclosure
- USB-C or HDMI interface
- power from USB-C?
- no battery or internals means it will be feather light and cheap!
- build in feet that pop-out; no stand needed
The trick is in the industrial design. All the ones on Amazon look like poo.
You have the audience. You should do this!!!
