My experience is exactly the opposite. I use the computer keyboard for input, and as most of the music is for piano, which spans several octaves outside the staves, absolute entry is a serious PITA. For vocal music, there aren't usually many wide skips, so again relative notation uses fewer keystrokes.
I'm sorry that this request has degenerated into a theological dispute as to the relative merits of \relative and \absolute. Both of them support different ways of working, and it's a question of which suits whom.
