There are already millions of computers like the Amiga in homes around the World. The fact is, very PC and Mac today has custom chips in the form of the GPU on the graphics card and the SPU on the sound card.
My Mac is used as a Media Center with Plex, Streaming 1080p content from the Internet or from a 2Tb external HD, using my iPhone as a touch-sensitive wi-fi remote. It's used for playing games with detail, resolution and gameplay Amigas could only dream about, for using the Internet, for everything. And it can hook into any TV or monitor available today since any new TV is going to have DVI or HDMI ports. And it's a third of the size and less than half the weight of my old A1200.
Why would anyone want to go back 25 years in time to a computer as limited as the Amiga when today's Mac can do 1000 times as much, 1000 times faster and for a fraction of the cost.
