I couldn't live without my Steelseries Qck+. I also think it's a little safer to use a mousepad because the glide pads (those things under your mouse) do not get a scratch that way. This depends on the surface of your desk though of course.
It can (CAN) also improve tracking stability in some cases. Most mice these days work fine on all surfaces, but it's the little things that count sometimes.
Had one of those too and liked it a lot, changed to a Gigabyte mousepad that came with this graphics card, it's basically QcK+ on steroids (larger, thicker).
Running a teflon padded mouse on a plain desk is a good way to ruin it prematurely.
I guess you are using an 800dpi mouse that would do just fine on a rock.
And my table is too slick to be anywhere near a good mousepad. I'd like to see you do some gaming (especially sniping) using my table as a mousepad and a 3600dpi mouse.
Matrixi, thanks for support. Also, can you change the sensitivity/speed of that touchpad? The touchpad I have on my laptop uses the same sensitivity as my mouse, so it's slow as hell.
Bose, I think that you can replace that "can" with a "will", especially on gaming mice. If the mousepads didn't increae the tracking stability, they wouldn't be produced, everyone would be using tables like Boris.
I do have adjustable dpi on my mouse but I like to set it higher, because I think there's no sense in buying a 3600dpi mouse and then using it on 600dpi. I mostly use 1200-2000, but it's still a lot faster than the touchpad.
