It sounds awesome. But again, since everyone is already familiar with the slider keyboard and used to it's look and function, the closer you can mimic that, the better! Even the shape, buttons, colors, etc...I wouldn't mind if the keys were exact. I would prefer it actually.

Oh, and if you do make sounds that are incorporated into the buttons being pushed, make sure you make one that sounds like your stepping on a wet sponge. That's kind of like the buttons on the keyboard now. Not the sounds but the feel. LOL
