A passive digitizer and a resistive touch screen are the same thing. what this means is the screen takes pressure as its input method. That means that anything that touches the screen can activate it, including your palm. The Asus t91MT has this type of screen but has software that rejects your palm so you can write like you're writing on normal paper…in theory it ends up slowing down the screen's ability to read your writing, distorting and skipping in your writing.

An active digitizer is a touch screen that activates only when a special pen is near or touching the screen. It responds much faster than resistive screens and means you can write on the screen with the same speed and position as regular pen and paper. You cannot user your finger to activate the touchscreen.

Capacitive is similar to an active digitizer but only accepts input from an organic object (ie. your finger). This is what is in the iPhone and it is very responsive and ideal for multimedia oriented touch screens.

Many tablets combine both an active digitizer and a capacitive/resistive screen to give dual functionality. However, this compromises screen quality and is very expensive.

I believe this convertible will have a sensitive resistive screen or an optional upgrade to a capacitive screen.
