No Student Discount on BT Mighty Mouse!

[Jiddick ExRex]

the Logitech MX1000 is a laser bluetooth mouse .. has up-down, left-right scrolling, and lots more buttons too

although i might consider giving mine up to get meself a BTMM to match the rest of my apple stuff

Is all of the MX1000 BT? I bought one when they first came out, and I do not notice anything bluetoothy about it...

Really? £43.48 (HE contract) and £44.xx (normal edu) on the edu prices where I'm sitting.

Same here. (£49 normal price)

Laser != Optical

It seems like this thread needs a little clarification about the differences between optical and laser mouse tracking.

Optical mice

An optical mouse uses a light-emitting diode and photodiodes to detect the movement of the underlying surface, rather than moving some of its parts as in a mechanical mouse.

...

Modern surface-independent optical mice work by using an optoelectronic sensor to take successive pictures of the surface on which the mouse is operating. Most of these mice use LEDs to illuminate the surface that is being tracked; LED optical mice are often mislabeled as "laser mice". Changes between one frame and the next are processed by the image processing part of the chip and translated into movement on the two axes using an optical flow estimation algorithm. For example, the Agilent Technologies ADNS-2610 optical mouse sensor processes 1512 frames per second: each frame is a rectangular array of 18×18 pixels, and each pixel can sense 64 different levels of gray.

Optomechanical mice detect movements of the ball optically, giving the precision of optical without the surface compatibility problems, whereas optical mice detect relative movement of the surface by examining the light reflected off it.

Laser Mouse

In 2004, Logitech, along with Agilent Technologies, introduced the laser mouse with its MX 1000 model. This mouse uses a small laser instead of a LED. The new technology can increase the resolution of the image taken by the mouse. The companies claim that this leads to a 20× increase in the sensitivity to the surface features used for navigation compared to conventional optical mice (see interference). Gamers have complained that the MX 1000 does not respond immediately to movement after it is picked up, moved, and then put down on the mouse pad. Newer revisions of the mouse do not seem to suffer from this problem, which is a power-saving feature (almost all optical mice, laser or LED based, also implement this power-saving feature, except those intended for use in gaming, where a millisecond of delay is significant). Since it is a wireless mouse, the engineers designed it to save as much power as possible. In order to do this, the mouse blinks the laser when in standby mode (8 seconds after the last motion). This function also increases the laser life.
