Latest Computer Accessories

Computer accessories have evolved a lot over the years, only the two main input devices haven’t changed much since they were invented. The QWERTY keyboard and the little box with a button on top that slides on the desk are tens of years old. Not so long ago the optical mouse suffered some modifications.
It’s called USB OPTICAL WHEEL FINGER MOUSE. As the name shows it attaches to your index finger, so you can work the scroll and buttons with your thumb, while the sensor at you finger tip detects movement, just like the classic optical mouse.

While it may have some advantages over the classic design, it get very uncomfortable after a while, your index finger gets sweaty. Another disadvantage is it’s poor precision, because the mouse – mouse pad friction is taken out of the equation, so it reacts more quickly to your finger’s every little movement.

For only $8 it’s worth trying out, it’s available at lightinthebox.com.

This latest computer accessory seems very simple and you would think that it’s an everyday plastic toy, but you wold be wrong. It’s a USB 2.0 hub for laptops, with four strategically placed USB ports, one on each mouse foot. This way there’s no interference between the ports, so any type of device can be connected of any size and shape. Standard desktop and laptop computers usually have ports too close to each other, resulting in unpleasant physical limitations when using the ports.

Ports face in four different directions when the animal’s legs are spread, permitting the full use of the ports, but of course only under the 5V 500mA total power limit. Four keyboards, four mice or four USB flash drives should work without any problems, but when it comes to external hard drives all bets are off. Even one hard drive could reach the limit and not start, because most of them were designed to work in one or two USB ports with 5W of power at their disposal. When connected through a USB hub, the hard disk has to share that little power offered by the port with the USB hub.

Other (so called) latest computer accessories just got a makeover, like this 2.1 speaker system:

The Edifer brand is very popular in China, it’s E1100 black speaker system is even more appreciated because of it’s unique design and great sound quality. Two satellites produce 4.5Watts of sound each, while the sub woofer delivers 12Watts. When we’re talking about efficiency however, these are not very good specifications, because the sound system’s rated power is 41Watts, meaning that it’s efficiency is around 50%. There are many electronic devices with even lower efficiency factors, but today anything below 80% efficiency can be considered wasteful.
