The images are a total rip-off of Kobo Aura and Lenovo Yoga. How about instead of batteries (what is this, the 90's?), it had solar cells built
into the screen (or at least on the back, on the opposite top margin, etc), and you'd never have to charge the device again? Because that shape is terrible.
And instead of USB it came with a small Bluetooth USB adapter for transferring files.
