After turning to Mac, in a sudden, I'm thinking why it's so attractive to me? When there are a lot of reasons like OS X is more stable, virus free (though partly because of market share is smaller than Windows) and so on, it's much more important to me that OS X has a great user interface. I got the impression from friends that Mac has a strong graphic engine, more powerful than PC. Since they are using similar hardware, then it's all about the beauty of software.
Personally, I'm using Firefox more for there are many convenient plug-ins. Hope it could catch up soon.
When 3D graphic control becomes a standard of industry and more web applications get involved, we are getting one step near to the Matrix world.
