MacRumors has today noted a few more details to come out of Apple’s recently unveiled ‘Magic Trackpad‘.

The first thing they note is that a few of their forum members have noticed that in order to use the new product, a software update is required. The update is now available from Apple.com for both Mac OS X, Windows 64-Bit and Windows 32-Bit.

To use the Trackpad, you need to install a software update that Apple will release later Tuesday. The software update enables full multitouch and gesture customization, including tap-to-touch and program-launching clickzones. Even without the software update, the Trackpad works like a regular non-multitouch trackpad. While Apple geared its full suite of multitouch gestures toward Macs, the Magic Trackpad will perform in its basic functions when paired via Bluetooth to a Windows PC–we tried it.

Next on the list is that as confirmed by @Macworld the Magic Trackpad supports a physical click, just like the Magic Mouse. They note that the click is instigated by the two rubber feet at the front of the device moving slightly.

Despite the Magic Trackpad’s thinness and its support for the same tap-to-click feature as MacBook trackpads, you can also click by pressing down. The trackpad surface itself doesn’t depress, though–instead, when you press on the trackpad, the force from the surface it’s sitting on will depress the two round feet at the trackpad’s base. That’s what registers a click.

Finally, @Engadget reports on a new three-finger gesture found when using the new device, which will allow customers to move windows around the screen effectively. It is also noted that this gesture is not yet present in Apple’s Macbook or Macbook Pro product lines.
