Awesome idea! Take the absolute worst thing about using smartphones/tablets, and apply it to desktop computers! I bet 90% of the people who get this will plug it in when their friends come around, then use a $10 standard keyboard when they actually want to use the computer. At least it looks purdy. 

So what's with the Ctrl/Cmd key icon? Looks like a guy bent over sucking his own pecker. Nice.

If it's using light, won't it register all of the fingers that I leave resting on the keys? 

Jeez... now touch-typing is a thing of the past. Everyone will have to watch where their fingers are. And why isn't that an LCD display too? Seems like a waste for not to be.

As cool and "futuristic" as this looks, in practice it would dramatically hinder your typing speed. Any of these projection/flat surface typing devices have this same problem.

It's the tactile feel that lets you type without looking at the keyboard. It's not just the feel of individual keys, but more importantly the tiny bumps on the F and J keys (or D/K, depending on your keyboard) that help keep your hands centered without having to keep looking downwards.

Unless the glass has some sort of raised surface or braille-like bumps to give your fingers a tactile map, it's going to end up like texting on an iPhone. You just can't do it blind.

man, yes 100%. its so obvious that i hope they make this and realize that they only sold 3 units and go bankrupt. it would be a good lesson for manufacturing complete bull-ish products

Check out the Kickstarter page. This does have bumps on the J and F keys, and sound tied to typing can be turned on or off based on your preference. Both of these features would make your valid point less of an issue for this particular device.

Only J and F key bumps aren't enough for a device like this one. Sound would not help much as it only tells you that a key was pressed, but without looking, you will be bound to making a lot of mistakes. I think the key boundaries should also be raised a little bit, or like Jonathan said, each key should be raised a little bit (although I wonder if it would alter the light reflection) and maybe also bump the symbols on each key. If we humans in general had perfect memory, to the point of walking around rooms blindly, then the J and F bumps might actually be good enough.

I agree with what your saying its the same thing when your typing on a tablet

exactly my point.

so how do you touch type on a piece of glass?

It's glass, right?

 Sooo......a spritz of windex [or cold tap water] and then wipe it off......not that difficult. 

The little white gloves come free, right?

If I've learned anything from using white Mac peripherals at work, it's that our hands are pretty gross -- even if we make an effort to keep them clean. This thing will be disgusting in a week. Cool design, though.
