Ask HN: Mouse or external touchpad

I like my Logitech trackpad but really I just want a keyboard/trackpad device exactly like the bottom half of my MBP for work.

I've always wanted to try putting a trackball on the floor, I've heard it is great for window selection. (I use focus follow mouse - if you are stuck on something other than a X this may not apply)

I don't know of any current computer that will not allow you to plug more than one pointer device into it. Why limit yourself to just one, get them both and see what you use. Some computers even let each device control a separate pointer which might be useful - or might be a big pain. Only you can know what will work for you.

I have yet to see an ergonomic touchpad. Although there are plenty of horrible mice to go around, too, there are fairly ergonomic models, and even special RSI-prevention models.
