There are many Tablets which use Windows as an operating system like the Windows RT Surface 32 GB Tablet, and Acer Tablets are some of the most popular currently used. This article is a simple review of some of Acer's most popular models which will show why they are often chosen ahead of iPads.
1. Acer Iconia W510.This tablet uses the newly released Windows 8 operating system and is one of Acer's best sellers. With Wi-Fi connectivity and 32Gb of memory, it is fast and efficient. The Acer Iconia W510 measures a handy and compact 10.2" x 6.9" x 0.4" and also has a useful detachable keyboard dock.Using the Intel Atom processor from the Clovertrail Generation, Acer has produced an excellent Tablet which is aimed at the lower end of the market compared to the i7, W700 and Core i5. With the release of this model Acer Tablets aim to rectify their previous poor performance reputation.
2. Acer Iconia W500. One of the best things about this Windows tablet PC for Windows 8 is that it is a true multitasking device. It is very easy to open two windows side by side, and you cannot do this with an Android or iOS tablet. The Acer Iconia W500 will run all your favorite software in its Windows 8, and there is no need to shell out extra dough as it comes with a detachable keyboard dock included. It also comes with an SD Card to store data and additional USB ports to connect any external peripheral. If you want a netbook alternative, the Acer Iconia W500 is here for you as it is responsive and smooth- you just need to be a little bit conscious about space. However, it is important to say that its onscreen keyword is rather small, which can make typing difficult.
In this article about Windows tablet reviews, we have talked about some of the most popular tablet PCs out there.
Instead of the CCD a Complementary Metal Oxide Semiconductor or CMOS can be used as the primary light sensor. The basic principles of operation of the two devices are the same. The CCD is made up of many light sensitive elements. These elements covert light into electrical energy, with more electrical energy produced in areas where the intensity of light is greater.

We can think of these elements as minute squares. Depending on the intensity and brightness of the light falling on the square, it produces a unique charge. Each of these square elements produces different electrical charges which are then carried by the electrical circuits to the location of the firmware. The firmware is configured such that it can interpret the variations in electrical charges produced by individual square elements.
The integrated firmware identifies the specific features of each charge and relates this information to aspects like color, contrast and brightness. This interpretation process is carried out for all individual elements of the CCD and the information obtained is put together to give you a complete photograph. The method involved in putting these details together is similar to the technique employed in televisions or computer monitors.
The picture is generated as a sequence of pixels, with each individual pixel consisting of three main colors. The Bayer Filter technique is used to vary these three colors to produce a variety of shades. Generally green may dominate among the three colors since the human eye is less sensitive to green compared to blue or red.
The firmware is responsible for digitization of the image. It produces a digital code which records the pictorial information. This digital code can be used to reproduce the recorded picture multiple times. This code can be transferred to the camera screen or other devices for hassle free viewing.

The basic principle used is the conversion of light to electrical energy. The individual elements of the CCD light sensor produce electrical impulses when exposed to light. These impulses are routed through the electrical circuitry and reach the circuit board of the camera. The circuit board of the camera contains the firmware responsible for digital encoding of the electric charges received. The firmware successfully authors a digital code which can be used to produce a detailed photograph.
The firmware programming nowadays includes code for image stabilization and other processing techniques which give you the best quality pictures possible. Since the photograph taken is basically in digital form it is easy to transfer and print. It successfully eliminates the need for long rolls of films and difficult processing mechanisms.
You should pick the size of your TV set in respect to the size of your room and the distance between your TV set from the couch (or any other place where you're going to sit while watching it). Most TV manufacturers actually provide 'standard charts' with recommended viewing distances for a given screen size. The recommended screen size does not directly depend on the size of your room. However, it does directly depend on the viewing distance from your couch.
Considering that the amount of maneuver space for your couch depends directly on the size of your room, we can say that the screen size and the room size are indirectly dependent (viewing distance is a mediator). For example, there is no point in buying a 60" TV if you're living in a trailer or a small apartment. Why? Because you simply don't have enough space for optimal viewing experience. Insufficient distance to your TV screen can have negative health effects as well.
If you're too close to your TV set, your brain constantly has to adapt to fast paced action scenes and graphics, which puts a lot of strain on your eyes and the area of your brain in charge of processing visual inputs. Our brains are actually great at averaging-out imperfections (this is obvious if you watch a low definition screen), but at a distance, not point blank! On top of that, some older technologies like CRT (Cathode Ray Tube) cause radiation concerns as well, because they emit a certain amount of negative radiation an inch or two away from the screen.
The following table can help the customers in choosing the right screen size:
TV Screen size (inches):
28, 30, 32, 36, 38, 40, 42, 46, 48, 50, 52, 54, 56, 58, 60
Minimal viewing distance (feet):
3.5, 3.75, 4, 4.5, 4.75, 5, 5.25, 5.75, 6, 6.25, 6.5, 6.75, 7, 7.25, 7.5
Maximal viewing distance (feet):
7, 7.5, 8, 9, 9.5, 10, 10.5, 11.5, 12, 12.5, 13, 13.5, 14, 14.5, 15
Customers can also look for a quite useful 'seat-to-screen viewing distance calculators' online on televisions for sale, and use those tools to calculate the optimal viewing distance for their room. In order to calculate the recommended viewing distance, the most of these calculators needs 3 input parameters: distance to main viewing location (feet), screen shape (standard or widescreen) and screen size. The customers can then use the calculated viewing distance to choose the right screen size for their room (by combining the results with their seat-to-screen distance).
If you want to calculate the screen size by yourself, the simplest formula would be to measure the distance from your sofa to your TV set in inches, and then divide that number by 2. This implies that you should sit 7 feet away from a 42" TV set. For every 6" more of screen size, add another foot of distance. Whenever possible, place your TV set directly in front of your sofa at eye level or slightly higher. Also, try to place your TV set away from the window, as the high light reflection can significantly decrease picture quality.
When choosing your optimum screen size, keep in mind that a 4:3 32" TV is not the same as a 16:9 32", meaning that you should purchase a larger widescreen TV in order to achieve the same size (40" or 42" HDTV).
