Even though Sony is the technology pioneer in the Li-ion field, as well as in many others, often they get caught up in their own little world and miss a boat or two. For example, internal politics (pride?) considerations kept them for too long tied up to the hard carbon anode while others were eating their lunch with the higher-voltage and higher-energy graphite. The 'not invented here' syndrome, perhaps. They lost a big piece of market share to Sanyo and Matsushita, but pioneers they remain, even though cannot always take full advantage of it. Sony's idiosyncrasies, you could call them A beautiful subject for a serious study. Jacques, the flat 500 cycles are always shown and quoted for a single cell under ideal lab conditions. However, when you have to string together 3 or 4 cells to get the voltage you need for a laptop battery, when you use the battery under all kinds of unpredictable conditions, partial charges and discharges, leave them in car trunks in July in Phoenix etc; when cells are never perfectly balanced and age differently, the capacity fade curve for a multi-cell battery looks quite a bit different.
