That's what you get with 3% global market share
I think that's more a result than a cause.
If Apple could acquire just a tiny share of the gaming industry, they could promote their platform for gaming.
They currently live on the fact that the graphics and music industry often runs on Mac, but even that is starting to fade out.
But it's also a virtuous circle. Apple doesn't invest in open standards like OpenGL, thus not gaining interest of developers, leaving Apple without interest to improve their game support.
Now that iPhone gaming is catching on, mobile gaming is rising aswell with good prospects for Android, webOS and Symbian aswell.
Apple is suddenly interested in acquiring EA shares to possibly fully acquire EA in the near future.
Also the fact that Intel is contributing to open standards is also very good news, as Intel powers the current Apple portfolio aswell.
It is also rumored that Intel hardware (x86) will power the next-generation Playstations.
The whole gaming industry is in turmoil. And hopefully the consumer will benefit.
I think that with a little patience, Mac gaming could actually be something in a year.
