as a guitarist i'm used to print outs like this. its very difficult to line up words and chord changes in a word processor document so whereas a guitarist can 'feel' his way, BIAB couldn't.

and with most tab sites you can get various versions - ultimate guitar has over 20 version of Ronan Keating's 'When you say nothing at all' and the quality varies.

ready made midis or BIAB files posted on line are at least editable. and by listening you can hear the quality. you won't know the tab is wrong until you try to play it.
