I used WP4.2 for the Amiga well into college. At the point that we were required to exchange documents with instructors in Microsoft Word format, my trusty companion became obsolete.
An Amiga, WordPerfect, and an HP DeskJet 500 can take you a long way. Just about as far as a C128D, geoWriter, and an MPS-1200 took me. Probably about as far as this guy's Pentium 233MMX with Windows 98, some old Word meant for 3.1, and his HP DeskJet (I tell him I can't believe his machine is still alive; he reciprocates the surprise :-D)
