Psion last week announced plans to revamp its older Series 3 handheld range with a new machine, while bolstering its newer Series 5 line with a new slim model. The Series 3 and 3A models are to be phased out, along with the low end Sienna PDA, in favour of the Series 3mx, available now priced at #269.95. A new slimline Series 5 is expected next year. The 3mx boasts a new 16-bit, 28MHz NEC processor that Psion claims speeds up the Series 3 by a factor of three. The unit comes with 2Mb of ROM storage, which houses the operating system and system applications, and 2Mb of RAM. Additional flash memory cards can be slotted into bays underneath the keyboard, expanding storage by up to 16Mb. The greyscale 480 x 160 screen now includes a backlight. One of Psion's strengths has always been its connectivity, and the 3mx uses the same RS232 serial port as the Series 5, allowing data transfers of up to 115,200bps between the unit and a PC. It also includes an IrDA infra-red port, which can transfer files or print jobs across a gap of up to one metre to PCs, printers, or other 3mxs. The infra-red communications software is fully upgradeable, but as yet is unable to share information with Windows CE devices. A Psion spokesman said: "We'd love to be able to do file conversion between these machines, but there are some technical issues." As Psion uses an MS-DOS compatible file system, transferring files to and from a PC is an easy process, and included in the PsiWin PC software are converters for the built-in word processing, spreadsheet and database applications that cater for almost every major productivity suite available, including various versions of MS Office, Lotus SmartSuite and Corel WordPerfect Suite. In addition, Lotus Notes, Novell GroupWise, Symantec ACT! and Microsoft PowerPoint are supported through PsiWin add-ons. Psion 0990 143050.
