no...not that you can feel....well...i can whoa...there was a specification for mice...in DPI? i thought that was for printers...if that 800 dpi is a spec, i bet it isn't anything.
And yea...in case you missed the sarcasm, wireless mice's batteries die on you in the most inconvient of times...
and i knew some one that had a trash can near the edge of his desk and he pushed his wireless mouse into the trash can and then he took out the trash.
