My mouse finally died yesterday. I'd push it in one direction and the arrow on the screen would go in another. No amount of cleaning solved the problem. Photo editing was difficult to say the least.

So I went to Walmart planning on buying one of the $5 cheapies when I saw this. I didn't even know what an optical mouse was. Got home and plugged it in and WOW! How cool are these? Has this little red light that tracks it. So smooth and no little clicky noises.

Do they have batteries? You can tell the level of my technological knowledge. LOL.
