The department of home affairs has less than a month to decide on a last ditch proposal presented to it by JSE-listed IT services group Gijima over the disputed “Who am I Online” technology project.

BlackBerry-maker Research In Motion has finally shown its hand in the tablet computer market, taking aim at Apple’s iPad with the PlayBook, a device with a 7-inch touch screen running the new BlackBerry Tablet OS. Aimed squarely at the corporate market – and thereby differentiating itself somewhat from the iPad – the PlayBook weighs 400g, has a screen resolution of 1024×600, sports a 1GHz dual-core processor, and supports true symmetric multiprocessing.

Gijima’s top line has slid 2,4% in the past year, reflecting tougher trading condition in the SA’s technology industry, says analyst firm Frost & Sullivan. Growth in managed service revenue did not quite compensate for a decline in professional service revenue.
