Logitech M570 Wireless Trackball Revised
October 21, 2010 | by techlineinfo.com
To get started, let me tell you the most common way to control a computer is through a mouse, but a mouse requires lifting your hand and moving your arm. Well, as a matter of fact a more ergonomic solution is to use a trackball, which lets your hand rest in one place. On the contrary you should also consider that trackballs aren’t as popular as a mouse, the Logitech M570 wireless trackball might make you change your mind.
In fact this wireless trackball consists of the trackball itself and Logitech’s tiny Unifying receiver that plugs into a USB port. Well, this elegant Unifying receiver works with all of Logitech’s other wireless products such as keyboards and mice, so if you lose it (which is easy to do since it’s so small), you can always get a replacement wireless receiver easily. This cool gadget lets you connect to both a Windows or Mac OS X computer from up to six feet away.
If you are looking for advantages then one main is of the small size is that it allows you to keep it plugged into a laptop computer without forcing you to remove it every time you need to pack your laptop back in its case. Its small size kinda makes it nearly flush with any laptop’s side so you can just plug it into your computer once and forget about it.
All you need to power the trackball, is just a single AA battery, which Logitech claims will last up to 18 months. (For your convenience, Logitech even includes a single AA battery that’s already installed inside the trackball.) And then to further continue conserving power when you’re not using the trackball, you can slide an On/Off switch to turn the trackball off completely.
No need to worry about using the trackball, it is extremely comfortable. Let me tell you how, to begin with there are four rubber feet on the bottom of the trackball hold it securely in place on almost any surface. Besides the traditional left and right mouse buttons and a middle scroll wheel, the trackball also offers a Back and Forward button for jumping backwards and forwards inside any browser such as Internet Explorer, Firefox, Opera, or Safari.
All these buttons, that is the Back and Forward ones worked automatically under Windows 7, but they won’t work under Mac OS X until you first download a free Logitech Control Center program, which lets you configure how the trackball behaves. Now, to make the trackball’s Back and Forward buttons work on Mac OS X, all you need to do is download free software from Logitech.
To round up the figure, the trackball’s shape is specifically geared towards right-handed users who can comfortably manipulate the trackball with their thumb while pressing the left and right mouse buttons with their index and middle finger. Don’t get tensed because left-handed users can still use the trackball, but it may feel more awkward manipulating the trackball with your pinky.
