Eat/Drink - sometimes, but only usually a snack (unless I am at uni, in which case I tend to alternate between eating my main evening meal and checking Internet sites!)
Listen to music - depends what I'm doing. I love listening to music when I am drawing, but hate it when I'm writing (I lose my concentration).
Talk on the phone - if I am getting bored on the phone, I may walk to the computer and start doing both, yes. XD This usually leads to me being rather quiet on the phone!
Watch television - sometimes, but I can't concentrate on both at the same time.
Play video games - not really. The odd Flash game perhaps, but that's it, and I wouldn't count that as a "video game"!
