Not really a mod per se, but I guess it's more of an improvement.
last night I was playing around with my mini and after a short while became aggrivated with the touch pad. I found that the texture on it prevented me from moving the cursor very small distances (sometime it would work, but most of the time I was overshooting it). Then it occoured to me to try using a screen protector that I purchased for my iphone... the one that was on my phone needed to be replaced with a new one anyway, so I took it off and cut it to size, applied it and the improvemnt is amazing IMO. Now it feels like a sheet of glass... figured I'd give you guys/girls the heads up.
I assumed that the suface of the pad might not let the sheet stick very well, but it's a non-issue
lmk if you decide to try it, I think you'll be fairly impressed
