Another important feature of the Hiptop2 is the ability to easily view the screen even without a backlight. All units until the LX model had this feature. Most other manufacturers utilized an LCD screen that was not visible without backlight. Hiptop and Palm Treo units (Treo 600 and later) utilized a transflective liquid crystal display that worked with and without the backlight, making the IM, mail, and all other messages readable even in bright sunlight, and without picking the unit up.
