From about 1992 - 1997 my brother and I ran a home-based design business mostly on a couple of expanded A1200s. We did some video titling work, some designs and prints for various media (business cards, menus, pamphlets, brochures, etc), some early web development, presentations with Scala MM. Back of office we were very fond of the Softwood products (Final Writer, Final Calc, Final Data), iBrowse and YAM for internet comms, and we sent and received faxes with GP-Fax.
My brother continued on a PC we got in 1996 to run a vinyl-cutter, and I moved to a Mac Quadra, then later a PowerMac, and so on. We kept the A1200s for a few more years for gaming and support for opening old customer files.
Edit: I forgot to add how reliable it was; Very. These things would run for hours on end. Whether it is some complex illustration in Art Expression, some 3D image renderings in Real 3D (in some cases overnight), graphics manipulation in ImageFX, or layout and postscript printing in Pagestream. I know the OS didn't have memory protection but the programmers wrote applications that played nice.
