LOGITECH T620 (` 4,295)
A regular mouse will let you touch the corner and summon the charms menu on Windows 8. But the T620 brings all the touch moves you do on a screen to your fingertips. Once you plug in the USB dongle of the mouse, a pop-up asks you to download software for the mouse. After the software is installed, think of the mouse surface as the screen. Swipe from the left edge and you get the apps menu, swap from the right and the charms menu pops up. You can also scroll horizontally and vertically by swiping on the mouse. There are also gestures to open the smart menu as well as to swap back. If you are looking at a touchmouse for Windows 8, this seems to be the best bet now.
