LIKE - I like this concept mainly because of its design consistency. It has a consistent rubber finish that gives the device a premium look. I like where the logo is situated as well as the edges have a great look. Over all the rounded edges and rubber finish gives the concept a new look I have not seen before. Also I like the size of the track pad.
DISLIKE - I mainly dislike the keyboard here. Although it does look good, it being made entirely out of rubber and plastic sends of alarm bells. As much as I like the surface pro 4 type cover, my biggest thing against it is its flimsiness. I guess that I worry that this keyboard will make the same mistake Microsoft has made.
LIKE - I LOVE THIS CONCEPT!! I like the premium metal design. The keyboard looks AWSOME!! I do worry that the trackpad might be a little small but everything else about the keyboard makes up for that. I love the texture look behind the kickstand as well. Sets the product out uniquely. I also like the back lighting, backlighting is almost a necessity for me and I am glad you included it. I also really like the power and volume look. I also like the different colors. Although I would not personally buy them I showed them to a few friends and they loved them.
DISLIKE - My main dislike for this product is the kickstand material. Having the tablet half rubber and half metal gives it an inconsistent design look.
I love the SHIELD and GEODE concepts, don't get me wrong, but I do worry about lapability #surface . I did not buy the original surface tablet because it would not work on the lap very well. Changing the kickstand to support different angles might help with this. Also if the keyboard is attached to the tablet very well and wont wiggle back and forth that might also help.
I don't like the others, not because of the look, but because of the way the keyboard attaches to the tablet. That does not even work for apple or google, never mind a windows product that one does real work with.
Anyways that's my bit. Hope that helps!!
