The GBA was the system that saved Nintendo.

The GBA didn't save Nintendo. The GC made ~2 billion in profit in its life and the GBA made about ~8 billion. Wonderful handheld though. I like it more than the DS and Gameboy.

You might want to check your numbers.

I think the GBA is highly inflated but I do remember reading that 80% of profits were made via handhelds.
