Simply making something smaller would never be considered 'revolutionary'. This is a lot smaller than either of my 2 bluetooth portable keyboards (my old Palm one and the iPad one), but not as small as the roll-up ones that feel terrible.

What would make this worth buying is if it feels great and is as small as they say it is. Would that make it revolutionary? No. 'best in class' but not revolutionary.

Related to the $ risk of investing at this point, agreed. Wonder what the overall success stats are... Anyone here ever actually invest at Kickstarter stage and then receive product?
