Logitech is the good sh*t!
I've got a Logitech NewTouch Compact keybaord, that is 3 years old and is still as good as it was brand new (this is now my keyboard at work).
I've got a Logitech Cordless Freedom Pro (USB, Cordless, Natural) Keyboard at home.
I've had many logitech mice.
[*]First Mouse + or whatever...2 button + 1 wheel, awesome mouse, 3 years old and going strong (sold it to a friend who had a crappy mouse).
[*]MouseMan Wheel USB, awesome mouse. It's sitting in my closet collecting dust now because it's not worth much to sell, but it's an awesome mouse and still works perfectly, 2 years old
[*]MouseMan Wheel Cordless (came with the Cordless Freedom Pro kb), I've grown to dislike the shape of the MouseMan for extended use, but it's handy to have a cordless mouse at time.
[*]Wheel Mouse Optical, this is my standard mouse that I use for most things.
2 keybaords and 4 mice all still working like the day they were born (manufactured)?
In my life I've also had the displeasure of using several microsoft mice, all of which broke...the new optical MS mice are nice enough, but the buttons feel a little mushy to me...the logitech mice have a much more solid click....
The MS keybaords are nice to, but I prefer my logitech.
