While I agree wireless mice are superior due to no cable and Logitech's implementation of wireless is faster than some extremely popular wired mice (like the deathadder 3G)... This video doesn't explain that or even bring anything useful to the table. I'm glad it was made, but I don't see t being useful for anyone.
People need to try good wireless mice, but the good ones are all also rather expensive, especially compared to wired equivalents as noted in the video. And even some pricey ones are shit (again as mentioned in the video, with Razer's wireless mice.) I know I probably won't ever go back to a wired mouse, and I'm looking forwards to Logitech remaking the G700 with their new g900/g403 wireless technologies and superior buttons.
