Actually, I only trashed a clutch, not a gearbox, when I was learning to drive and learning stick at the same time, and if someone had told me that I shouldn't have done what I did that caused the clutch to explode, I wouldn't have done it, and I wouldn't have trashed a clutch (I was always very smooth with the clutch, I just made a shift that I shouldn't have, preparing 1st gear for when I'd have to go again, and didn't realize that, even if the clutch pedal is pushed in, so the engine will never see those speeds, ~8000 RPMs isn't good for the clutch on a diesel.)
But, yes, I learned to drive on a stick, and it probably made me a better driver.

Learning stick when you learn to drive also means that it's ingrained in you, and you can probably pick it up again later. From what I've seen, people that learned to drive on an automatic, then learned stick later have trouble driving stick if they haven't driven one in a while, whereas those that learned to drive on a manual, even if they've been driving only automatics for years, tend to be able to pick right back up where they left off.
But, that's offtopic.
