Finally, I'd like to say that features like the bat signal should be included in Windows 7, but disabled by default.
The problem there is that if it's in the box, it has to be tested. Any time there are UI changes, it has to be tested again just to make sure a change in another area didn't break that feature. That can get expensive. If it's not something they think many users will use (and by many, I mean it needs to be in the millions considering the size of the install base), they'll yank it so they can concentrate their efforts on other features that more people use often.
Vista sucks for not encapsulating the exception
And how does your favorite operating system deal with fatal errors while in kernel mode?
