HoTMeTaL Pro
Tish. Dreamweaver & Frontpage were pretty bad. Whereas HoTMetaL Pro (note the capitalisation) produced good code fast and you could slide between pure code, illustrated code and full preview at a mouseclick. So far ahead of its time it was a threat to all the wannabees.
Hence Corel bought it up and closed it down. It still lives on in a Win2K VM as I still have some customers running sites developed with HoTMetaL who refuse to pay me to redevelop them as 21C sites and now revel in the retro-glow of people who surf the interwebs to the sound of authentic vinyl music and dodgy cigars. And flares, don't forget the flares ...
One of the last pieces of software I paid good money for. Like all the other good software the developers would be bought out and your investment wiped out. Whereas if you stuck to FOSS then if it was any good software could survive death, debilitation or monetisation by some other good soul forking it. Better deal in the long run I found. Free isn't always about price.
