I have this laptop stand that I have used for many years with my MacBook Pro. Since I recently shifted to an iPad Pro and am leaving the laptop behind, I started using this stand as a lap table for the TextBlade and my iPhone.
It works pretty well. I put the TB on the front, and I use the TB stand for my iPhone (landscape mode only). Portrait mode for the phone on the stand tends to tip over. This is a lot more stable on my lap than I expected it would be. I have been using it to type while riding the subway to work.
I'll send pictures sometime next week.
