Disruption occurs when the incumbent more than meets the needs of its customers ("overserves"), and the entrant meets those needs well enough - and also meets the next-most important need of customers. (A very simple model of customers is that they have ranked needs - once the first-ranked need is met, they focus on the second-ranked need etc) So, mobile phone voice quality is not as good as landline quality, but good enough - plus, you can use it wherever you are. Microcomputers are not as powerful as mainframes, but powerful enough - plus cheaper and smaller. While some customers in some circumstances may still need the extra quality/power of the incumbent, the big profits go to the disruptor. Do console graphics overserve most customers? If not, how close are they to it? (Note: while there is obviously room for improvement, the key question is whether customers want that improvement. If they are overserved, the improvement just doesn't matter.) Apart from the popularity of casual games, one test is that PC versions of games have better graphics than current consoles - yet, the console editions are outselling them. It seems that customers value something other than graphics.
