My husband's laptop was slippery because his hands were a little wet with perspiration. Not much but enough that he lost his grip and the laptop almost hit the ground. Luckily he caught it just in time before it smashed on the tile floor.
Now I had to find something to put on the case and went on a search for whatever it was that I was looking for. You know the game, you know it when you see it. After a diligent hunt I found Grip-It-Strips at grip-it-strips.com. Scratching my head wondering how these things work, I read the page and decided these were exactly what I was looking for. My order finally came and I had a great time designing something on the laptop.
