Hmm, as someone else said earlier -- the space bar is a little weird. I'm not sure if it's broken, or if it's just supposed to be this way. It seems to be working normally as I type this, but it still feels weird.
It's like you can wiggle it and it'll pop up and down like a normal keyboard; or, like it is now, it just kind of stays pressed down and you just tap it to make a space -- it doesn't really move very much. It kind of sticks.
