basic mice

The interface to PowerPoint is seamless and excellent. I especially like the "6 o'clock" button that blanks the screen (the "b" key on the keyboard--did you know that feature of PowerPoint??). There are billions of ways you can configure it, but it works great out of the box. The buttons it has are quite useful!

The laser is rather weak. If you have a white background, the audience cannot see it. The laser is well collimated, so it makes no difference if you are 1 foot from the screen or 30.

The flash memory key is a good idea on paper, but our group has only been hampered by it: Windows (by default) sees this device as an empty floppy disk, so if the numbskull that is giving the talk decides to reboot the PC, the reboot freezes until you remove the key/flashmemory/antenna. (It took me way too long to figure THAT one out).
