I really like the small size and weight of the 400D. So much lighter and more pleasant to carry than my 1Ds it's unbelievable. Image quality is basically indistinguishable from the 10% more pixels of the 1Ds (I usually feel like there is actually a teeny bit more detail in the 400D pictures, suspect that has something to do with the way the software processes them). High ISO performance is noticeably better than my 1Ds.
Two things I don't like:
1) The viewfinder on the 400D is awful. I cannot tell at all when something is in focus with the viewfinder, I use autofocus confirmation as has been discussed in other threads here lately. Manual focus by eye just doesn't work at all for me. This is a very serious drawback for someone who does a lot of macro. If I'd known about it, I would've gotten a 20D or 30D instead.
2) The 400D doesn't have the second control wheel on the back. You have to hold down a button near the viewfinder and use the main control wheel (in front of the shutter button) instead. This in itself is a pain in the butt, but it is worse because the button you have to hold down is VERY close and just to the lower right of the viewfinder. I am left-eyed, and the result of all this is that if I want to adjust exposure compensation, I have to use that button, and the natural way to use it is to stick my right thumb up and depress it. Only problem is that about half the time I try this, I stick my thumb in my right eye!

So if I have to be VERY careful when doing this, or more likely take my eye slightly away from the viewfinder. This is a nuisance, but not as serious a flaw for me as the viewfinder.
End result is that I consider the 400D very acceptable for a second camera (and the small size is even a significant advantage for this), but for a primary camera I think the 30D (or an old 20D, etc.) is a better deal, especially for someone who does a lot of macro. My old EOS 10D was much more convenient to use, and the viewfinder was less intolerable for manual focus. In your case, Ken, I'd recommend you save the money towards that 5D instead. I've not used a 5D viewfinder, but if it is anything like the 1Ds, you won't believe how much difference that makes. First evening I had the 1Ds, I put a 50mm lens on it and sat in my easy chair watching tv through it, it was so large and clear!
(I just went back and reread your post--For your friend, if he's only modestly going to be into seriously playing with exposure compensation, and won't use manual focus, the XTi is probably a pretty good deal IMO). But he should be aware of those issues. Also, if he is right-eyed, I think the exposure compensation issue won't be nearly the problem it is for me.)
