The amazing thing to me about the wireless remote is that they actually figured out how to make it work without wires! How do they do that? did canon come up with that tech or was it an adaptation from tesla?
the only down side is that you can't do some things with it like you can the wired remote...
like....
tie up your models ( or art directors )
play jump rope ( you could pretend to play jump rope with the wireless one I guess )
look cool while reelling in the wire and wrapping it around your hand while bragging about how big the files are from the 1ds3
hmmm.... what else?
