Re: @Thad Do you remember....
" used to work with/for a former Ashton Tate/Borland employee/refugee and he told me it was a pun on "1-2-3", by using Spanish... Uno, Dos, Tres... Quatro, but they used two "t"s in the name."
I always thought it was Italian, which does have two "t"s. Audi also made the Quattro spelling well known.
I really liked Ami Pro but for me the Windows version of 1-2-3 was the first spreadsheet I had ever used and it kind of sat there like a dumb thing without giving me any hints how to drive it. Fine for existing users, not so good for a novice IMHO.
In contrast Quattro Pro did give me hints how to drive it, especially with the way right click produced context sensitive menus, It remained my favourite spreadsheet for a decade.
The last version of 1-2-3 I worked with was in 1996 and someone somewhere had decided that table pivoting was a job to delegate to Approach. It was truly painful to watch an animated graphic displaying "connecting to database" (client server architecture being the latest buzz phrase then) and then see it fall over in a heap. After an hour struggling with that I slipped the data onto a floppy, took it home and did the job in 15 minutes flat on my home system using Quattro Pro.
