It's a smaller market than a CPU and likely requires same or more effort. As a person not interested in gaming I would prefer the resources to be used to develop better computing experience. I understand the pool of people who can do such things is not unlimited.
Current CPU market is in dire straits as Intel was bumbling the last few years and only now AMD is catching up, but it seems like Apple is already miles ahead.
That wouldn't be too bad, but it means the market may be won by a company that is anti-consumer, anti-competitive and two faced.
