FWIW, I've been annoyed in the past by sluggish response caused by fontification upon display; not recently though, i'm not sure if that's because of stealth fontification or not. I'm not referring to "total paging time" or any such thing, btw, just a sort feeling of "lag" upon entering a new screen (often when I've used i-search to skip way ahead in a big file). I don't have a good feel for the tradeoffs though. I think the problem is for most people one of perception more than anything else -- yeah the laptop case is an exception to this. -Miles --=20 Do not taunt Happy Fun Ball.
