Mouse bandwidth? Let me read that again. No, it's true he said "mouse
bandwidth". My Logitech Trackball came with a USB to PS2 adapter, and I
can't tell any difference in the way the pointer moves around the
screen. Will it be necessary do do a "double click" in slow motion
because the "bandwidth" is so slow? I have to research this. Does CNET
have a Mouse Bandwidth Meter? How many Kbytes per second should the
average mouse run at? Maybe I need to beef up ALL my systems to get
greater mouse speed! Damn, the speed of my mouse has been holding me
back all these years.

Oh, maybe I just made it up. The rest of the world is switching from PS2
mice to USB for no reason at all. You don't get more accurate mouse
pointing with USB. Just because you can't notice a difference doesn't
necessarily mean you're "slow" yourself... or does it?
Sarcasm aside, the baud rate for a PS2 mouse is much lower than a USB mouse
(9600 vs. 1.5M). That means that while it's moving, the tracking is more
accurate for the USB mouse. The PS2 mouse should "catch up" within 32 bits
(3 ms) of stopping, but for accurate dynamic motion the USB mouse rules.
