Just to tell my opinion:

I tried Aros on an old PC with an that had an nvidia grafikcard and a 1,8Ghz cpu. True that was a few years
ago but the system doesn't run stable old amiga software didn't work. I played around for several month
and lost interrest on it.
I had thought about buying an Amiga again but they where to expensive for me and from what i read they
had not even a feature rich browser.
On linux I used OnlineTVrecorder frequently, and what a surprise there was a decoder for Morphos from which
I knew it was a next gen. Amiga system - and its hardware was much cheaper since supporting old macs.
So I bought a Powermac MDD and payed the 111 Euro after having a very easy installation, not to compare
with the most linux or even Windows installers. No gfx driver the soundcard was specified the network came
up with no trouble.
As a beginner I took the papiosaurus software package. The System was better then my old Amiga 4000 060/32Mb
Cybervision ....
And it cost less then 300 Euro (in 2011 and that was the Hardware + System).
You can't get an old Amiga 1200/030 32Mb w/o gfx card for that prise.
It still is an impressive system, not to talk about the Powerbook - !! an Amiga Laptop !!
Only Morphos can run such a thing and its really cheap and (mac hardware) reliable.

well thanks for reading ...
