I guess looks can be deceiving, it’s hardly ‘normal’.
What your mouse choice comes down to, though, is your personal mousing style.
How do you hold the mouse? Do you rest your palm on it, or do you use your fingertips? (me: fingertips)
Would you actually use buttons beyond left and right click and the scroll wheel? (me: no)
Do you use your arm to move the mouse or your fingers and wrist? (me: fingers and wrist)
How far do you move the mouse to get the cursor from one corner of the screen to the diagonal opposite of the screen? (me: 19 inch screen: < 2 inches)
When I bought the Copperhead, wireless mice just didn’t have the resolution & reliability to allow me to be as lazy in my movements as I wanted to be, this may have changed - however, to save on battery life, wireless mice turn off when they’re not moving. In my experience, with my less-movement-is-better style, this resulted in my violently shaking the mouse in order to wake it up - frustrating, to say the least.
If you palm the mouse, a giant one is a good choice. Either the MS Explorer or the Logitech VX Revolution (I’d go with the VX)
If you want portability, the Logitech VX Nano is a great choice - the tiny receiver is never in your way, doesn’t block other USB ports and it’s not at risk of being broken off.
If you game, something from Razer might be a good choice.
Bottom line: you’ll have this mouse for years, it will most likely outlast this computer and the next two: spend the money to get a mouse you’ll be happy with.
