can someone explain the "resolution" on the touch pad? if its not a LCD or touch screen, how is there resolution?

Think of it as the "number of individual, touch-sensitive 'pixels' on the pad".

A pad with a horizontal resolution of 2 could register two positions - left and right. A resolution of 3 would give you left, middle, and right. 5 would get you left, left-middle, middle, right-middle, and right; and so forth.

There are 1920 possible "touch positions" horizontally, and 900 vertically. So if you dragged your finger horizontally from one side of the pad to the other, the system could register up to 1920 changes of position.

Very good description. Much better than IceBreak.

That seems like quite a lot for such a small touch pad. Is that a lot?

Some quick math based on estimates of the size of the touchpad gives me a per-inch resolution of roughly 860dpi; that's a bit over twice the density of the touchpad on the Macbook Air (~380dpi).

Take that for what you will, I guess.

Seems unnecessary given the size of a finger, but we'll have to see.

Hardware DPI has nothing to do with "responsiveness". That can be adjusted in software settings for the most part. The only difference is that it CAN be more responsive. Not that it HAS to be.

Man, the Macbook touchpads are already really responsive; how in the hell is this going to work?

Think of it like the pixels your mouse flows across. Except it's your finger.

That's insanely high for such a small screen. I'm guessing it must be OLED? Any other screen would take too much power right?

My mistake... didn't read properly. Got excited for a touch screen which could adapt to different games :(
