I've had a laptop using the octane 17.3 case for about 2 years and in general I'm very happy with it, one issue I do have is that the trackpad seems to randomly lose it's responsiveness , possibly due to oil/acid from my fingers - I seem to have had similar problems with most laptops I've had in that the track pad surface wears away. I was wondering if anyone else had had similar issues , or knows if there is a way of replacing or upgrading the trackpad (or whole case) ? Thanks
