interim CEO thing doesn't seem to be too hard at all. Thomas Seifert, the temporary solution to the problem created by Dirk Meyer's departure from AMD's top spot, has had a pretty comfy ride reporting the company's latest quarterly results. The pecuniary numbers themselves ($1.65b revenue, $375m net income) were tame and unexciting, but Seifert got to make a pair of juicy milestone announcements. Firstly, on the mobile and ever-so-efficient front, he noted that 1.3 million Fusion APUs (Accelerated Processing Units) have been shipped to partners since AMD started deliveries in November, and secondly, in terms of discrete graphics chips, he disclosed that the Radeon HD 5000 and HD 6000 series DirectX 11 GPUs have surpassed the 35 million units shipped mark. To give you some perspective on what that means, sales of Nintendo's bestselling Wii console are hovering somewhere around the same figure. So yes, AMD, your wagon has momentum, but shouldn't it have a driver too?
