I think they get a lot less slippery with use, but the only time I would ever call the leather cases grippy is when my hands are sweaty or clammy, in which case they will sort of stick to the leather. Some people always have clammy or moist hands, but my hands tend to get dry, especially during winter, and then the Apple leather is no longer grippy, even after using it for a year....the leather is only slippery the first week or so but after that, once it starts to absorb the natural oils from your hands, it becomes super grippy.
