Alright guys I have the v470 in hand and used it extensively for a couple days and I found it very smooth but it does take 2secs to reconnect when mb is asleep. The laser is positioned on the right side of the mouse instead of the usual left so movements were a bit awkward. I felt my aim to be slightly off in games due to the laser positioned. I'll do a more thorough review on both mice when I recieve the Kensington in the mail. I am also typing on my iPhone so a review isn't that fungo do on here LOL. If you guys have other Bluetooth mouse that you use please post your feedback here. Thanks and stay tune for the update!
