On another note, I Think Steve is mistaking "Fudging a roll" for "Not letting PC's die, ever." Fudging a roll to save a PC means not letting that specific PC die in that specific instance. With you're standard 4-person group, one person dieing can cripple things. And it's one thing to die as the Boss is going down, it's another to step into the dungeon, and get taken down by a Greataxe Crit to the face. It's not a matter of the player crying like a baby, it's a matter of them wanting to do more than sit there for two hours while their buddies struggle to kill some orcs because they lost their wizard. I can almost imagine the following scene
DM: Ooh, it looks like that kills you, here, I'll just have it knock you into negatives.
Player: okay.
Jolly steve: *Bursts through a wall* NO! THE DICE SAID YOU DIED. TAKE IT LIKE A MAN! DO NOT ACCEPT THIS CODDLING. IF YOU CAN'T HANDLE THE HEAT, GET OUT OF THE OVEN!
Or, for another situation . We are in a fight, the PC's are winning, but the fight has gone alot longer than the DM expected. The DM wants to finish the adventure this session, so he fudges in the PC's favor so they can win faster and move on.
Remember, the first rule of DnD is "Have Fun". What you are saying is that every game of DnD with every group will be more fun without fudging rolls. Unless the group in question consists of "Little Kids". Yes, some groups may prefer putting themselves completally at the whim of the dice, they may prefer a game where, if the dice say you die, you die and the party just has to make do. And for a group like that, a good DM will not fudge rolls.
However, some groups would rather beat the dragon due to a few fudged rolls, than die horribly by playing strictly "By the book". I know that if my DM fudges a roll, I've forgotten about it thirty seconds later. I don't think "Man, I know we beat the dragon, but it dosn't count because the DM fudged that saving throw"
