when it comes to mice, they are useful depending on the situation. Surfing the web is fine w/ the trackpad while I would cry trying to work in Photoshop or Flash w/ a trackpad only. So it depends on the situation and you.🙂 I carry a mouse with me all the time just in the event I find myself in the situation where I need it.
Currently, I use a corded mouse, it gets me by...but I know a fella that has a BT mouse and he just pulls it out of his bag and it like connects seamlessly as soon as he turns it on. Look into it, Logitech and Microsoft mice are mighty nice.🙂
