Asustek's plan to promote and build the Asus brand has always involved splitting the company into three distinct units, and it looks like the company has finally gone ahead and taken that step -- say hello to the new Asus, which only makes Asus-branded computers, Pegatron, which will handle OEM, mobo, and component manufacturing, and Unihan, which will concentrate on casing, modules and other non-PC manufacturing. Pegatron and Unihan are expected to continue the former Asus' manufacturing tasks with little to no dropoff or transition, but there's a nasty little surprise in store for employees of all three new companies: their former pensions have all been cancelled, and the clock started anew as of January 1. No wonder they named these companies after rejected Decepticons.
