which is better optical mouse or conventional wheel mouse....

i have tried both and i can say is that optical mouse is much more convenient than the conventional wheel mouse because since i've bought my optical mouse last may,i still hasn't change my mouse since then.unlike,my wheel mouse i just used it for a couple of months and then i have to replace it again because the ball is getting out of place and my kids are getting the ball out of the wheel mouse so when it's time for me to use it,there's already no ball inside.

OPTICAL FOR ME

I like my conventional. But others here like the rolling ball. I cant stand that so we have 2 mouses that sit on our desk and we have to change them out when we want to use the one we prefer.
