Im sure when that day rolls around, Apple will have their own console, and i hope sega will.
They've pretty much perfected the games graphic wise, all they have to do is let nintendo get up to speed and work on user immersion. Faster load times, smaller systems, handheld resolution, Imagine a handheld wii, Like kirby tilt and tumble except much better. I have a feeling they'll all join together at one point, and make a console to end all others.
As for that disc changer idea, its a pretty good one.
And they have to lower prices to get more purchases
