I'm contemplating selling my 40D, my 10-22mm, my Tokina 35mm macro....and using some bonus money from last year to bump up to used 1Ds Mark II as its replacement. I love the way the 1D's feel in my hand, and a lot of my photography takes place out doors at (or near) the beach. The added weight would not be an issue, IMHO.
But I'm wondering if a used or refurbished 5D Mark ii might be a better use of my funds, since they seem to price pretty closely together. I like everything about the 1Ds II....except the lack of HD video. And so with a 10month old son now, that's probably the one place that gives me pause. But it's not a deal breaker, as I have a nice Flip HD recorder that keeps the wife happy with some nice home movies of our little guy.
I don't have any compelling urgency to go full frame right now. But I'm finding that for family outings now with my son, my 35-350mm is on my camera quite a lot....and that lens is just a much better fit on a full frame camera (especially on the wide end). I have a good enough lens arsenal now that a switch to FF wouldn't demand any immediate need for new lenses (check gear my list below). What attracts me to the 1Ds is the weatherproofing -- I live about 2 miles from the beach and my son seems to REALLY like going there! 
Anyhow, I have a couple friends local with 5D's and 1Ds Mark III's....and, of course, they are gung ho about going FF. But none of them owned the 1Ds Mark II. So I'm hoping someone here who's owned both the 5Dii and 1Ds Mark II could offer some personal comparisons.
Thanks,
Matt
