Still monochrome, the 115 by 40mm viewing area displays at a resolution of 480 by 160 and, like the original Revo, doesn't have a backlight, so it's unusable in areas with minimal lighting. Data synchronisation and backup is intuitive and quick. The unit can be charged directly or through the cradle via a power socket on the 9-pin serial connector. It takes less than two hours to charge the unit and the two integrated 700mAh batteries last for around 14 hours. There's a 23mm speaker built into the side and while sound quality is good, it would benefit from an increase in output volume.
Software is the key improvement .
WAP capability is integrated. Trivanti, a joint venture set up by Psion and United News and Media, provides a WAP browser and SMS connectivity. The WAP browser lets you set up a range of service providers and bookmark pages, while SMS lets you send and receive text messages from the Revo Plus to a mobile phone or pager. Psion hasn't corrected most of the faults that held back the original Revo, though. For those who want an electronic organiser with a keyboard and who are concerned about portability this is a good option.
