I have the Magic Mouse 1 (the one with replaceable batteries) and I've used it with a mousepad for some time. However, I got sick of the poor traction and glide speed the Magic Mouse has on the mousepad. So I decided to put the pad away and use it on the desk. This is what everyone I know does. After using it like this for a while, it was a lot nicer. The mouse moved a lot quicker and smoother. However after a few weeks, I noticed a lot of small white specks on the desk where I used the mouse. At first I figured it was just gunk that built up on the mouse and flaked off. After a bit I decided to clean it off, but noticed that they were not coming off. So I put my glasses on and inspect them. Turns out the texture of the desk is being chipped away by the mouse. These specks are the color of the wood showing through the texture. Some of the larger ones even are lumpy. Now this desk is fairly cheap, it's just a particle board, but I've never seen anything this bad. I looked at the mouse, and it's in good condition. No scratches or chips. So now I'm back to using it with a mousepad. This is a real disappointment to me, as it felt a lot better to use. Any good mousepad recommendations for the Magic Mouse? Here's a picture of the damage --- Post Merged, Aug 10, 2019 --- Just saw I posted a thread similar to this about 4 months ago, but it was about the mouse getting scratched. I did look into this, and it turns out the fins were already chipped and the dust was just filling it in. I have poor eyesight so it's hard to tell what's old and what's new. I also said in the post that the desk was fine, I wish that was actually the case... Sorry for posting about the same issue twice, I honestly had totally forgotten about the original post.
