They don't make it anymore, sadly.
I loved that it held my 7 inch tablet and worked with it wirelessly, and that the hinge was stiff enough to hold it up as I used it on my lap or standing on the subway. If only the keyboard was weighted it would have been stable to put on a table without the kickstand in the back, but that was a fine compromise given everything else it delivered for not a lot more money.
I hope your Pinephone experiment goes well. I'm optimistic for them.
