First post here, thought this is the right place for this. I have been prototyping a "Surface lap holder". As the name says, you snap it your lap, it forms a mini-table, you put the Surface on top. there are slots to slide the bottom edge and kick stand in. I have got the close to product prototype, tested pro and rt. It works. Sturdy enough to hold the Surface (pro or rt), while typing on the touch or type cover. On one lap only. You can however put the other lap closer but no need for that. Generally working with one lap. Size is exactly a A4 paper fold in half. Weight: 110g (Lumia 920 weighs 185g, Lumia 521: 124g). Foldable, when folded, 0.25" (6.35mm), that's the thickness of a single DVD case. So it's very portable. Safe to say you can put it into bag and forget about it. I want ask the community, whether there would be any interest. Projected price in ($18-$20), made of strengthened nylon. Put it straight forward, if I make it, would you/anyone buy? Honest answer, please. You would help me a lot buy sharing your opinion.
