Resolution: No Better
The resolution is still 800 CPI (Count Per Inch). This is the number of images used in determining the speed of the cursor movement in relation to that of the mouse. The higher the resolution, the shorter the distance the mouse will have to move to produce a given movement of the cursor on the screen. For the MX 1000, then, a maximum of 800 measurements per inch are sent to the computer. The perception then becomes a matter of screen resolution. The higher it is, the slower the mouse will be at a given CPI. To be brief, 800 CPI is only usable at a very high resolution, 1600x1200. Below that, most users will have to lower the speed, which is done via a cursor in the mouse driver program. By default, the cursor is set to approximately 500 CPI.

No Cord, No Latency
The MX 1000 uses the Fast RF technology for wireless transmission. The frequency is still 27 MHz, but the frequency band has been doubled. The advantage lies in being able to transmit twice as much data and thus to refresh the coordinates twice as fast. The disadvantage is that the broader band will also be more sensitive to external disturbances, but Logitech has the problem under control. In practice, transmission is never interrupted under normal use conditions. With the speed of Fast RF, the mouse is capable of transmitting its coordinates more than 125 times per second as compared to 50 for a conventional cordless mouse. The 125 figure is cited because it is also the maximum speed possible with the USB connection, and therefore there is no point in increasing it. In the final analysis, the MX 1000 communicates as rapidly as a corded mouse, and without latency.
