> and at that price I feel that there are plenty of companies who would bite Google's hand off.

What does this expression mean? Does that mean that companies would think this is too expensive? or companies would jump at the chance to buy YouTube for 5 Billion?

It's not clear at all to me what you mean and I'm a native English speaker:)

If someone offers you a sandwich then you take a bite. If you are particularly enthusiastic or quick to react, you take a really big bite and bite their hand off.

It signals extreme enthusiasm and keenness. I hear it all the time (UK).

Ah, that makes sense:)

Thank you.

i think he means any company would jump on it.

it's like giving a hungry dog food. the dog would bite your hand off, along with the food.
