Tranny / differential fluids - when to change?

I've asked around the dealerships and also online, but wanted to get feedback from you guys that actually did the above 1 or 2 fluid changes, when you did it, why and at what intervals? Did you look at the old fluid/related parts to see that it was requiring a change? I understand that the tranny fluid is sealed, but still, just because of that, it shouldn't mean 'lifetime'.

I wonder why BMW says these 2 fluids are 'lifetime'? The cynic in me thinks so when the engine/differential 'tears up', they can rack up in service fees. 'Lifetime' can't be true especially for those of us going over 100,000kms/60,000 miles.

Thx in advance.
