There is no new system on the market today that compares to the original Amiga system developed in the 1980s.
It could be possible..
I want a complete system where the hardware and the operating system work together. The hardware should be powerful, but energy efficient, and not require a giant tower case with lots of fans and NOISE!!!
The operating system should be responsive, and not freeze up when accessing the hard drive. The audio should play properly with no clicking. You should be able to play video in a window and move that window around while the video continues to play.
The applications should be small/compact, possibly with an IPC(?) system like AREXX, and maybe a component object model system.
When a new system like this comes on the market.. I will buy it :-D
