What are you taking about?.....The G5 (and I'm sure its the same for the Copperhead) put the cursor EXACTLY
where you move it. Its more percise that anything I've used before it
I'm sorry but you have no basis to say "avoid at all cost". The laser mice have been extensively tested, by people that know how to judge and have been given nothing but praise. Never a mention of the non-sense you are describing.
On the subject of non-sense...I've read this line about 10 times;
Negative acceleration is when the mouse cursor travels more when you move it slower, as opposed to faster but by the same amount.
and can't for the life of me figure out what you are trying to say.
