This clarifies the doubt from some users that saw in a demo somebody touching the OQO 02 screen.
...the 02 features numerous improvements over its predecessor. It's up to four times faster, and has a significantly brighter display (up to six times brighter than the model 01). The improved keyboard is now backlit and has capacitive TouchScrollers for easy navigation. The model 02 also provides an array of wireless connectivity: EV-DO Wireless WAN, 802.11 a/b/g, and optional EV-DO 3G support.
