I have a VX Revolution from Logitech and a wireless Aluminium keyboard from Apple, the latter is extremely responsive, but I am coming in terms of the mouse being less responsive than I want it to be. I dont want to get the magic mouse as I dislike Apple mice. I have a Wacom tablet on my desk, but that's used for other purposes. Using my MBP in the clamshell mode is great, but the unresponsive mouse is killing me. I don't have a cell phone nearby, so that's not the issue. Receiver is well close enough to the mouse. So the question is: ergonmic 2 button mouse with a wire (I use a USB hub). Bluetooth mice are quite expensive so don't want to get into that, unless...there is something good that's worth the cash. Thanks!
