Synaptics' chief scientist, Shawn Day, is close to releasing a phone fingertouchpad for writing Mandarin characters--an easier way to key in a mobile text message (the Chinese send millions of them every day).
Particularly compared to the touchpad, which falters at single-finger navigation, the pointing stick is impeccably precise when it comes to moving the cursor around screen.
Moving on, the external touchpad is a Magic TrackPad competitor if ever we saw one, with support for all the multi-finger gestures you're used to making in OS X.
