The touchscreen community has been pretty unsympathetic to the fat fingered crowd. For people with sausage sized digits, pressing one key on a touchscreen keypad is usually accompanied with the pressing of a second button and the escape of a fucking expletive from their lips.
The TAD Custom Finger Mod slides a ring on your finger with an attached screen poker for easier keypad navigation for those of us with bloated paws. They offer up to size 0.7-inches, so anything higher than that and you either have to lose some weight or get some dialysis to relieve that water weight. Get yours for $6. — Andrew Dobrow
