Myself, I never saw the point of maxing out an A1200, i.e., Mediator, PPC, 256 MB RAM, 2 TB HDD, USB, Towers to put all that stuff in, and the list goes on. One (not you, necessarily) could get an A4000(T) with same chipset and end up spending around the same amount of money. They were made for upgrading.
OS 4.1 is not meant for everyone, certainly not for gamers or Retro enthusiasts. It is a modern OS with strong underpinnings of Unix/Linux. It has elements (Python for example) that modern OS's use. It does behave like the original Amiga OS's but is predicated on a PPC. It hogs RAM (common to current OS's), but has a beautiful display, very nice modern enhancements, and has become my main OS on my Classic Amiga. I know it runs better on the NG Amiga's, and if I ever get together enough cash (or sell one of my "maxed" A4000T's) I would get an x1000. In fact having a PPC accelerator you picked up years ago and really never used, IS a good reason to run OS 4.1 but only if you really, really want to.
