Rooster,
Good points -

4. I love the backstraps for the M&P - but the XD has the thumb rest that works perfect for my grip. On the M&P I still haven't found a grip or palm swell I perfer as my support hand thumb gets lost and finds itself getting in the way of my shooting finger.
Yes. That depression in the grip of an XD is nice.

5. The trigger on both guns are nice - I still really like the XD trigger better at this point, but from reading gun books I'm learning my trigger technique is wrong and I'm having to change, so I'll have to re-analyze this point at a later date.
I recommend that you have Burwell Gunsmithing perform a trigger-job on your M&P. He lightens the pull to 3.5 pounds. It makes the trigger nicer than a standard XD40 in my opinion.

6. The magazines seem better on the XD - this could be apples to oranges, but the M&P40 magazine is much harder to load than my XD9 or my previously owned P345 .45 caliber. My poor thumb is hurting... The XD mag seems to go in and out smoother too.
You are pressing more volume into the M&P magazine and getting the same round count (15), which I consider impressive. You will find in your studies that the force required to load a magazine is not generally considered a significant factor in magazine quality. How well it feeds rounds into the pistol is very important.
Also, you may have noticed in my list that my XD40 magazines change shape over time. This is more of a hassle - but I really don't like the fact that I have flatten the front of my XD magazines every month or so.
Solution to hard magazine loads: I recommend that you purchase a speed loader. After you get used to it, loading a magazine is easy and fast. I use an HKS Speedloader for my XD40. I need to try it on the M&P40 Mec-Gar magazine.

7. The S&W seems lighter and thinner - however looking at them side by side doesnt seem to confirm this - both seem the same width, but the M&P seems thinner? Either way, I like the thin feel of the M&P...
I noticed the same thing. The width is really similar, however, the feel is much "thinner". This is my theory: The M&P is longer in the slide, and is less of a block shape than the XD. Also, the front-strap of the grip is much more narrow. The feel is more like a 1911 than an XD. The end effect is a pistol that is easier to get into and out of a holster. Try inserting your M&P into an XD holster. It will go in with less force.

By the way take a look at the M&P refinished by Burwell Gunsmthing:
