One of the biggest new features in the new MacBooks that Apple just unveiled is the glass trackpad, one that ditches the button in favor of turning the entire trackpad into a button. It also works with a bunch of new gestures, using up to four fingers to make doing things like switching between applications and flipping through a photo slideshow easier. It's pretty cool, but definitely not as cool as the concepts we've seen with a screen underneath, making the whole trackpad-is-the-buttons much more logical. Where's the screen, Apple?

Anyhow, this new trackpad has 39% more of a surface area than the old ones. As for the new gestures, some of them will include things like a two finger gesture to pinch and rotate for zooming and panning, a three finger gesture for swiping between photos or a four finger gesture for expose and app switching. Of course, all of this could have been done with the old plastic trackpads, making me wonder what, exactly, is the benefit of a glass trackpad with no screen underneath. I personally prefer the feel of my plastic trackpad to the screen of my iPhone for dragging my finger around on, as there's less resistance and fingerprint-gunkery on plastic.
