I was a bit unclear. I was asking about the keyboard, not the mouse. Anyways, the response time of the keyboard is fine, but it seems that when it has to "queue" up key commands, it will lag when it gets towards the end of the command. For instance:
If i wanted to type: I am visiting anandtech for the very first time today"
The instant i type "I am" the characters will appear normally. BUT, once it gets to the "very first" and on, the appearance of characters will lag.
