I had the same questions before I dove in. For me it was the OS. If you look at the x5000 as a general computer for everyday use then it's going to lose to every option you put against it, but when I started thinking of it as my main Amiga computer that can play all of my classic software flawlessly that's when the paradigm shifted for me. When you really play with OS4 in the ppc environment and not an emulated one, you get that nostalgia back in a huge way. Maybe that's what it ultimately is. Look at it as having the best Amiga computer today and not the best computer.
No need to defend yourself here on Amiga dot bloody org! It's not Apple.org here (it does not even exist, they only think .commercial)
You got a damn well nice equipment
