Symbol is to drop Palm operating system (OS) devices from its range, it confirmed today.

The move comes as Palm is being taken over by Motorola in a $3.9bn (£2.1bn) deal announced in September.

The move follows another firm, Access, recently dropping the Palm devices from its range, despite having bought the OS owner, PalmSource last year and who is focusing on Linux-based software.

A Symbol spokesperson said the move was in response to growing acceptance and competition from Microsoft and its mobile OS. It will cease to two Palm OS-based handhelds - the SPT 1550 and SPT 1800 – used for industrial scanning operations, but support the OS until 2010.

The spokesperson added: “While the Palm OS-based series of products has been very successful for Symbol, component parts have become obsolete and no longer available.”

Palm fell foul of the new RoHS Directive for "the restriction of the use of certain hazardous substances in electrical and electronic equipment", which came into effect on 1 July.

Symbol could not upgrade several of the components of its SPT 1550 and SPT 1800 and discontinued the devices, in addition to the Treo 650 smartphone, which befell the same fate earlier this year.
