Seems a little overzealous to install little plastic tabs on your controller, even if you do wanna up your KD ratio.
Being honest, I own a pair of the FPS Freeks, and I really like them. They don't cost much at all and they really do add a lot of precision to the controller. I may seem like a crazy, but they make the controller feel a lot better for both FPS's but also other games say FIFA for example which is something I say is worth it for only $10.
I just wear gloves when gaming on my xbox LOL I can understand where people want control the grips wear down thumb slips and stuff I would just get new tabs for it though
For the PS3 they have little extender buttons that add a little lip for the main buttons on the front of the controller - otherwise your fingers slip too much... those look like good ideas since fingers do slip off the thumb joysticks... I always wondered why they did not come with little clips like they have on the pedals of racing bicycles...
You're not the only one; I use gloves for my PSP because I can't stand the fingerprint-y plastic the whole darn front panel is made of.
If fingerprints on your iPhone/Touch bother you so much, buy a fingerprint proof screen protector. I have one and it works great. I can't imagine wearing Gloves while playing.
Fixed. You only need one new computer each generation, much like you only need one new console each generation.
