Optical Mouse Versus Laser Mouse
The optical mouse’s popularity boomed in the late 90s when it started being shipped as an extra feature to many computer systems. The optical technology became increasingly popular among users because it made working with the mouse much easier than with the traditional ball mouse. Since then finding a regular ball mouse has become somewhat of a challenge.
So how does the optical technology actually work?
The optical mouse is equipped with a light emitting diode (LED) and photo diodes which it utilizes in order to detect movement relative to a surface i.e. a mouse pad or a desk top.
Essentially, the mouse is equipped with an optoelectronic sensor (a small low-resolution video camera) which takes successive images of the surface on which the mouse operates. The images of the surface that the sensor takes are captured in continuous succession and compared with each other to determine how far the mouse has moved.
The modern optical mice work on most surfaces. Some exceptions are glass, mirror and other specular surfaces.
The color of the light emitting diode (LED) of the optical mice is usually red simply because red diodes are inexpensive but it is not uncommon to come across blue light emitting diodes either.
Unlike ball mice optical mice don’t have any moving parts which leaves almost no room for mechanical malfunctions and optical mice are less breakable.
The light emitting diode of battery-powered wireless optical mice only glows steadily when movement is detected. The rest of the time it flashes intermittently to save power.
So what’s the difference between the optical mouse and the laser mouse?
Instead of using a light emitting diode the laser mouse uses an infrared laser diode. The small infrared laser the mouse is equipped with significantly increases the resolution of the image taken by the mouse. The laser enables around twenty times more surface tracking power to conventional optical mouse technology.
Glass laser mice (a.k.a. glaser mice) can also be operated on mirror or transparent surfaces.
Since the laser diode the mouse employs emits infrared light it’s usually invisible for the naked eye.
So which one is better? The optical or the laser mouse?
When answering this question we should consider the DPI(dons per inch) each technology is able to track.
On the one hand, the common range for the optical mouse starts from 400 to around 800 dpi.
On the other hand, the range of the laser mouse is often above 2000 dpi. The ability of laser technology to track such high dpi makes the laser mouse much more precise and accurate when compared to an optical mouse. That added sensitivity is why most professional graphic designers and gamers prefer the laser mouse rather than the optical mouse.
In conclusion, the laser mouse technology is arguably the better one. I say arguably because some users find the added sensitivity rather distracting while simply browsing the Web or checking their email.

Asus Zenbook UX31
Considered as one of the first laptops to conform to Intel’s Ultra-book specification is the Asus Zenbook UX31. This product has just been recently launched this year and it is competing with those products dominating the market right now. This product surely does give the Apple MacBook Air another tough competitor in the best luxury ultra portable title division.
Asus did one excellent job with the design of this baby. Although at a glance the design gives you sneaky peek at Apple’s design with the MacBook Air. This wedge-shaped laptop measures 17 mm at its thickest and an amazing 3 mm at its thinnest. And did we just mention how sleek this laptop’s design is?
This laptop has a distinctive concentric circle design which made of aluminum silver lid. This lid actually catches and reflects the surrounding light which somehow gives that premium look every time you lift the lid.
This gorgeous design also comes standard with an SSD and 1600 x 900 display. This boost can give you plenty space to scroll through those web pages and documents of yours. The UX31 will also surprise you on how crisp movie playbacks can be with it. The viewing angles in this laptop are just simply impressive.
It is but inevitable though to compare this to the MacBook Air mainly because of its design. But the details of what makes each of the products tick definitely make the difference.
When you open the lid, you will notice how the metal keyboard keys are carefully crafted. You can consider the keyboard as sturdy as it looks and it’s a good thing that got that not-too-slippery finish that is just perfect beneath those fingers. As you type your way through the keys, it gives you that quite low-pitched sound that gives you an idea of its quality. Although one strike this UX31 gets is that the keyboard is not back lit. This may not be a big a deal to many but to those thinking of getting a MacBook Air will get the edge in this area.
Battery life of a laptop is one of the things that we always would want to consider. The UX31 will not fail you in that department. This product can hold out five hours and 41 minutes before charging it again. This is also another area where the UX31 matches, if not beats, the MacBook Air. But you’ll be surprise to find a longer battery life which is seven hours with only light usage.
How to Find a Good Cheap Laptop

Software Developers Make the World Great
Nowadays there are about one thousand companies that are accredited by Apple and other producers and are given the green light to produce mobile applications for any device based on iOS or Android be it a phone or a pad. Software developers from all over the world are trying to win the attention of the audience and to give them the applications they desire. In fact, this is not easy to accomplish. The degree of competition is really high and one new company tries to damp the previous average prices. But for the end user this is really great!
