The video below is from tablet-based blog Carrypad and gives a demonstration of the ‘palm-rejection’ feature of the forthcoming HTC Flyer.
Palm rejection describes the means to press on a touchscreen whilst using a stylus without interfering with the activity of the stylus. This seems to work pretty well in the video below; while the Flyer is in pen mode, the demonstrator presses the tablet with his finger while continuing to draw with the stylus.
