When I'm using my laptop for any length of time I grow tired ofusing the trackpad. I almost always keep a travel mouse with me, whichis a good alternative, however, if you do't have a good mousingsurface you may want to look into this Swiftpoint SLIDER.
This tiny gadget is actually a mouse, or at least that's the closestthing I can compare it to. There are a couple of ways to hold it,either grip it similar to a pen (shown above) or you can lie it downand move it with your thumb sitting on top of it. It will work on mostflat surfaces, including on top of your laptop keyboard. I'll use mytravel mouse on the palm rests just below the keyboard, but that's notalways enough room, so this would certainly give you a larger area towork with.
