Logitech has done a fine job bringing computer mouses to the market that at least partially compensate for the lack of a touch screen on a Windows 8system. Unless you have just purchased a brand new all-in-one system or notebook with built-in touchscreen, chances are slim to none that you own a touchscreen display that adheres to Microsoft’s requirements. With the t620, Logitech succeeded best in our opinion: this mouse offers serious added functionality for Windows 8, that in our experience you will actually use and enjoy. The t400's extra functions are far more limited, too limited to really consider this a true Windows 8 mouse.
Logitech recently introduced two mice which it developed specifically for use with Windows 8. The Logitech t620 Touch Mouse and the t400 Zone Touch Mouse offer extra options to at least partially compensate for the lack of a touch screen on existing systems. We got to grips with both mice for a few days.
The t400 Zone Touch Mouse is the cheaper of the two, with an average price of about 36 pounds. This relatively diminutive mouse (it measures 4 x 2.4 x 1.2 inches) is available in red, black and blue. In all models, the top is dark grey. This mouse has two regular buttons, but in between you'll find a touch sensitive strip. That serves as a scroll wheel, but it also offers additional functions, which we will discuss on the next pages.
The t620 Touch Mouse is the more luxurious and versatile of the couple. This mouse features a larger touch sensitive area, that covers the entire top side. There are no visible buttons, but the mouse does actually click when you tap it at the front on either the left or right side. Because it has a larger touch area, the t620 offers more touch functionality, which we get into on the next pages. The t620 is significantly more expensive at around 59 pounds.
Both mice have a wireless connection and come bundled with a Logitech unifying receiver, which you insert in a free USB port, where it extends at most 0.2 inches from. This receiver can be used to connect up to five compatible Logitech devices. Both mice operate on AA batteries, there is no charging station for either. To save power, there is an on/off switch located on the bottom.
Logitech markets the t620 and t400 explicitly for use with Windows 8. It goes without saying they offer functionality that seamlessly integrates into the way the new operating system works. Particularly the t620 has a few interesting touch gestures up its sleeve.
Using standard settings, you can use the t620 to open the new Start screen by tapping twice with one finger on the middle of the mouse. Use two fingers rather than one and you open the desktop environment. This way, the t620 offers an equivalent for the Windows and Windows + D keys on the keyboard.
Swipe from the left side to the right on the t620 and you can switch between Windows 8 applications, in a similar fashion as you would do on a touch screen by swiping from the left side of the screen to the right. There is no good keyboard equivalent for this gesture and as such the t620 definitely delivers additional value with this function. Mind you, you can only switch between active full-screen applications. By swiping from the right side of the mouse to the left, you open the charms bar. That is definitely a faster way than moving the mouse cursor to the corner of the screen, so that is another plus for this mouse.
