Going wireless is a wonderful techinical trend, especially if you still bogged down by heavy compenents with an endless amount of wires underneath your desk. Having so many wires was driving me up the wall! Constantly getting tangled and intertwined, I opted to purchase a wireless mouse. Microsoft 3000 is ergonomically designed for comfort and manuevers well in either hand with ease. Located on the bottom, is a compartment to snap in the receiver to turn off the mouse to reserve on battery life. Other features include 4 button to easliy navigate through pages (the small arrow is the "back" button. Don't press the arrow if you're writing a review, beacuse you'll lose all your work and have to start over, like I did). There is a battery indicator that warns you when its low, high definition optical warrants smoother tracking, precision, a fluid response, and it works well with PC or Mac. The battery is included in the package, so no need for buying a double A. Having a wireless mouse is awesome! I can take it anywhere and use with any pc, because there is no installation, just plug and play. No cd required. I bought my mouse at Target for $19.99 on sale, but I found the same exact item on-line for $24.99. It's better to check in-store stock before forking over and extra $5 bucks, plus you have to pay shipping and handling charges, which can catapult the price to over $30.00. They come in a variety of metallic colors; green, pink, silver, blue, purple, and basic black to fit any mood. Stripping my pc from it "apron strings" enhances my workspace appearance and decreases my chances for in house accidents. No more embarrasing cords. Functional and practical.
