I never got a track ball for my laptop because apparently they don't sell a wide selection in stores anymore. They just aren't popular anymore so no one wants to stock them. I went online and looked around and I think I'm going to buy this track ball (also pictured below). I hate to buy without trying it out first. But I don't seem to have a choice. If anyone can recommend a better one, please let me know. Otherwise I'm going to go ahead and order it.
