I seem to be in the minority of those of us who have both a DS and a PSP, because I usually reach for my PSP between the two. I do agree that for being on the go the DS is much sturdier less of a pain to start up and play here and there, but I just enjoy playing the PSP so much more, as well as the other features of the system. Load times have never really bothered me so much, though I definitely find myself using the PSP when I have more time to sit and stare at it.
