@rubenerd in a post, you mentioned that the C64 could only do 40 columns of text. Ackchuwally, about that... There was at least one word processor that supported editing in 80 columns, unless my memory is playing tricks. A quick search returns some corroborating results.

Of course, it wasn't the most legible text, you could do a lot with a C64, but magically double its horizontal resolution wasn't one of them...
