Just making a short comment here, you'll still need to do this on 
grub-legacy if you want to default on windows. Still a PITA too. An 
alternative is to set default to saved. And yes, it's slightly more of a 
hassle to do that in grub2.

One way to avoid all this is to set up a separate 'main boot' or first 
boot partition to boot all OS. Any changes made in that grub.cfg will 
not be affected by any OS grub-update. Also it eliminates the need to go 
to each individual OS grub to update kernel changes in the other OS's.

But the main advantage is that for testing new OS or alpha's; where, by 
its very nature, is prone to errors or is 'unstable', you'll may end up 
with an unbootable system if this unstable OS is set to mbr and is 
nuked. Having a 'main boot' partition avoids this as it won't be nuked 
by any OS, even if that OS is nuked.

Oh, it's always a good idea to keep a grub2 rescue disk handy. It was 
PITA to make a grub-legacy rescue disk, or setting a 'main boot' with 
grub-legacy and maintaining it. Or when the system cannot boot. Give me 
grub2 anytime.
