Removing the trackball ring from a T-Mobile BlackBerry Curve BlackBerry-maker RIM recently decided to do away with the trackball completely in its latest lineup of BlackBerry smartphones, opting instead to go with a more reliable optical "trackpad" with fewer moving parts.
A trackball can be thought of as an upturned mouse ball with surrounding buttons. You move the pointer on the screen by rotating the ball, and click as you would with a mouse.
A touchpad, on the other hand, is a section of the laptop surface which is sensitive to finger movements. You move the onscreen pointer by touching the pad and swiping with your fingers. One advantage touchpads have over trackballs is their construction. A touchpad consists of a few thin layers of capacitive material, while a trackball uses physical contacts to detect the movement of its ball.
To remove the ball, just pull it out or flip the Expert Mouse over. Dead-skin gunk accumulates underneath the ball, as it does with every trackball, so we recommend doing this every couple of weeks.
Instead of a scroll wheel, the Expert Mouse has a scroll ring around the ball. But the scroll ring felt gritty when we turned it, as if two pieces of metal were skimming across each other. The ambidextrous design works for both right- and left-handed people.
To correct for this, the Expert Mouse comes with a detachable leatherette-covered wrist rest to prop the hand in a neutral position. This accessory makes the Expert Mouse over 9 inches deep, so it might be too big for some work spaces. The accompanying KensingtonWorks software allows you to customize button behavior, scroll speed, and pointer speed, as well as to set shortcuts for pushing two buttons at the same time.
You can also set up a keystroke to initiate a precision mode that slows down the cursor, and you can customize button behavior per application. Otherwise, the Kensington software has the same basic features as Logitech Options and is equally easy to use.
In contrast, the Logitech Ergo M is the best of the bunch we tested, with up to 24 months of life on a single AA battery. The Expert Mouse has a power switch on the bottom but can also trigger a sleep mode automatically after inactivity to save battery life.
The Expert Mouse is expensive, but its build quality and its four programmable buttons make it worth the price over the Kensington Orbit with Scroll Wheel, which has only two buttons and is available exclusively as a wired model. Kensington offers a three-year warranty for the Expert Mouse, in contrast to the one-year limited warranty Logitech provides for the Ergo M At 40 mm, the ball is smaller than that of the Expert Mouse 55 mm but bigger than the one in the Logitech Ergo M 34 mm.
As a result, you can use it on multiple-monitor setups, but you may have to bump up the sensitivity more than on the Expert Mouse. You can clean this model the same way as the Expert Mouse—just pop the ball out and wipe any gunk inside.
Although the scroll ring is chintzy plastic, it felt much smoother to scroll than the gritty wheel of the Expert Mouse. The Orbit with Scroll Ring is comfortable to use right- or left-handed, and the two buttons on either side of the trackball are easy to reach. The Orbit with Scroll Ring comes with a five-year limited warranty. It uses the same KensingtonWorks software as the Expert Mouse.
Comfortable to use and easy to get the hang of, the Ergo M is a good choice for new trackball converts. Plus, it includes Bluetooth and USB wireless support. If you prefer a thumb-operated trackball, we recommend the Logitech Ergo M If that is the case , might be the sensor in the trackball is already defective, try to get rid of that sir, head on the service center and ask them if they can fix it, i think black berry does not providing parts.
