I don't get IM on the computer either. I've used it some in the past, but usually, about 5 minutes in, I start thinking I should just pick up the phone and call instead! 30 minutes on IM or 3 on the phone, with voice inflections! So, yeah, I don't get it.
Oh, and don't get me started about the size of those KEYBOARDS! --> <-- You gotta be kidding!
