&gt;  are you really getting anything done more efficiently?<p>Maybe not, but is that 200ms improvement when using the mouse really worth it if i get all warm and fuzzy-feeling by being able to type something? :p Intangible benefits, yo.<p>More seriously though, i also feel (personally -- maybe i&#x27;m an outlier) like switching from keyboard to mouse and back is a bit of a performance hit, so i tend to concentrate my workflow around the keyboard as much as possible.  And yeah, maybe (99% certainly!) i&#x27;m not the leetest or fastest h4x0r out there, but at least i&#x27;m enjoying myself :).<p>(i would be curious about an actual test case though -- maybe someone could design a few common tasks to complete using one&#x27;s favourite HID and compare!)
