R61i How different from R61?

[Neil]

I've been putting together a R61i over the past few weeks, and finally have it working (though not completed).

Just have a point of curiosity really. What does the "i" represent? At first I thought it might be for Integrated Graphics, but some regular R61 models have the same graphics chip, so that's not it. So, I'm still left wondering, what's the diff?

Hah, I'm curious too.
My R61i is equipped with Nvidia's faulty GPU, so it's definatly not about integrated graphics.
