Psion has put PC application functions into its latest palmtop, the chequebook-sized Psion Series 5. Equipped with PC integration software, it is compatible with Windows 95 and Windows NT files that enable users to share files and synchronise data with a desktop computer via cable connection. The palmtop was being targeted at professionals who want to manage business and personal data while on the road. An integrated messaging suite with Internet e-mail, fax, and digital cellular short messaging will be introduced later this year. The Series 5 also sports a touch-type keyboard, touch-sensitive back-lit screen, stylus and a digital voice recorder that can double as a dictaphone. Weighing in at 350 grams, the Series 5 can run up to 35 hours on two AA batteries and comes in 4-megabyte or 8-megabyte versions, expandable to 10 megabytes using a CompactFlash card. It will be available in Asia-Pacific this autumn.
