I think many actually enjoy the build/customization process. Amiga OS isn't too user friendly by default, but it's also ancient.
I recently put a 1200 together mainly for WHDLoad, and didn't have too much trouble getting things setup.
1. Made a boot disk with HDInstTool, PFS3, and FAT95/CFD
2. Used said disk to format and partition hard disk, reboot
3. Coped contents of 3.1 "Workbench" disk to bootable partition, installed files for CF use, reboot
4. Had already built and tweaked 3.1 install done on the A4000 (could sub UAE here), transferred WB install and games via PCMCIA card, reboot and enjoy
Not that my Amigas haven't caused endless headaches in other areas...
