TeX vs Troff
I have been using TeX for some time now, I used to use troff earlier. Books like those from Tanenbaum and Richard Stevens still use troff where as authors like Ullman have migrated to TeX/LaTeX. The troff authors mention that real authots still use troff. I am confused now. Troff is simple to use, but TeX is very powerful and fits well into the pdf, especially with context. I find it difficult to draw pictures using metapost, where as pic is quite simple.
