Once upon a time, the Amiga was at the head, technically:
- CPU, sound, graphics
- Operating System
Then other machines caught up (since the Amiga didn't improve: it took them 7 (!) years to release a major upgrade, AGA chipset to the original one). So people started to say "ok, other machines can do nice things, but the AmigaOS is better anyway, cause Windows sucks, and started to argue around the OS.
Then other OS caught up as well (and went far, far beyond), so, well, what do we have now ?
- slow and un-adapted CPU for desktop use
=> it consumes a lot more than desktop CPUs (of course! It's designed to run 24/24 in a printer, routers (well, no, routers now mostly run ARM cpus))
- outdated OS
=> it boots faster (of course, it provides way less services, and I don't even talk about security, stability, lack of protection,...)
25 years ago, people were arguing about the Amiga's superiority.
Today, people are arguing about Amiga's inferiority. I wish people started to be humble, construct something really superior, and designed for its use, not some underpowered embbed stuff slower than a smartphone before thinking about superiority...
It's a fact: Amiga has lost every superiority... Now couldn't we live with/accept that ?
So yes, when you run 50 servers 24/7 power consumption is important. But as my desktop computer, it never was that important.
And about the PS3: it consumes way more than SNES. So it must sucks, right ? Even though it must consume less than a traditionnal PC, today's consoles (apart from the Wii maybe) are power hungry... This is a fact too.
