These are all tangible benefits for most users. Let's face it, the Amiga as a hardware platform is not modern.
What is it then? An antique? No, a Cray 1 is antique, or all the other machines that came before it. In the 80ties computing changed. Nice and simple machines that you plug in and can use. That is modern is to me. In this sense new computers are just more of the same and nothing else.
The modern era of computing didn't start a few years ago, but a few decades. Don't confuse power and extended features with modernity, it's about the essence.
A good example is modern medicine. It's not a couple of years old, but started a relatively long time ago. Sure we have more advanced techniques today, but medicine 50 years ago was already modern, and it could be argued that it was decades before.
It's easy to call something not modern because it doesn't perform as well as machines of today

Try running AROS, amithlon or even just UAE on a current "peecee" and tell me you don't find any advantages at all.
Yeah, it will be faster. If I want speed, then I'll just do it on my peecee. To me it's about using an Amiga, and if I find something it won't do fast enough (or badly because of crappy software), then I'll use something else. Speed on my Amiga isn't all important too me, and my Blizzard '030 is fine (wouldn't use an '060 much, for example).
