Everything you need to know before buying a Tablet

While some time ago the Tablet PC concept was aimed at those consumers with greater purchasing power, because only the leading brands offer this product on the market, as the case of the Apple iPad, the fact is that in the last years the furor over this new technological article led to the emergence of economic tablets developed by recognized brands, and the emergence of hundreds of models of completely unknown brands, most of Chinese origin.

However, given the wide variety of brands, models and prices that can be found in the tablet market, it is often difficult to know which of all these products we can buy assures us that is truly suited to our needs and requirements. So here are some of the fundamental aspects to consider when buying a tablet, either brand or those known as generic.

Prerequisites

An aspect that in principle we should evaluate is the autonomy offered by the device. Consider that a tablet is purely portable, so the battery life plays here a more important role. Therefore, it is best to choose a product that offers us at least six hours of battery life at least.

It is also important to include the charger, as some generic brands does not include this accessory with the tablet, what forces us to buy the charger separately, increasing the final value of the product.

However, at present the charger is not a must-have accessory, thanks to mini USB connectors included in most modern tablets, which allow charging the device from any USB port.

The operating System

Another major aspect focuses on the preinstalled operating system. On which it is advisable to opt for tablets including Android 4.4 minimum. At this point it is advisable to buy a tablet that has at least version 4.4 of Android, although in the case of a much earlier version, it is still possible to obtain a very important benefit of them. It is noteworthy that the most recent version of android is 6.0 Marshmallow.

It is also possible, by not having the latest Android operating system, that these devices are cheaper.

Also, for some time, we have available in the tablet market with Windows 10 preinstalled as operating system, at a very attractive price and good hardware, which assures us that we can use most of the applications we use on PC Microsoft Office as well as other tools such as connection to a local network and others.

But, why the operating system becomes so important? Well, primarily by applications available to them and compatibility with the other devices we have. Consider that the functionality of the new device will depend largely on the possibility of finding tools for each of the tasks we do with the tablet.

If we are users of the services of Google, and we have a Chromebook, Android phone and other devices to fully exploit tools Google, we should not hesitate a second: The best choice is an Android tablet, due to compatibility between different Android devices we have.

Now, if we are not completely tied to Google, a tablet with Windows 10 will be a good choice, as it will behave like a notebook.

Other considerations

Besides the type of operating system, autonomy and other technical aspects, we must consider other points, that although they are not essential to the proper functioning of the tablet, can orient itself a purchase to a particular type of device.

It is essential that the tablet give us the possibility to connect to the Internet via Wi-Fi, and it is worth thinking about purchasing a tablet that also support the 3G or 4G protocol.

Other considerations to consider are the size and weight of the device, as sometimes be enough motive for us to decide not to buy a particular model. It is therefore essential that we evaluate the use we will give to the tablet, so on that basis also choose a team of 7-inch or a 10 inch, as this varies considerably weight and size of the device.

The same goes for the autonomy of the device. While more autonomy possesses a battery, this will be larger, and therefore have greater weight.

In this sense, the ideal for those who plan to use the tablet as a calendar, to read books, check email, surf the Internet, use social networks and others, most recommended devices are the 7-inch tablets, while for those who used the computer to viewing videos and movies or to play it is advisable to try a 10-inch tablet.

Beyond the size we have chosen to the screen of the tablet, it is best to opt for a tablet whose screen is of the capacitive type, because it offers us a truly productive and pleasant tactile experience. Either way, find a tablet or phone with resistive screen today is almost impossible.

On the other hand, if we have a device that meets our requirements, we observe and analyze the kind of speed offered by the processor of the tablet, and at this point we should not acquire a tablet that run at a slower speed of 1.4 GHz. Also should include 1 Gb. of RAM minimum.

Another important aspect to consider is the storage capacity that holds the tablet that we will buy. It should be noted that most of this type of equipment includes an internal memory, which it should not be less than 8 Gb, and also offer the possibility to expand the storage capacity with micro SD cards, so you should endure at least 32 Gb card.

Note that if we are users usually store many files like documents, music and video, eventually the storage space provided with the tablet will be insufficient.

That is why if it is within our budget, we buy the tablet with greater storage capacity possible. Another alternative is to make sure that the tablet possesses the necessary memory cards support 64 Gb or more.

Dispensable requirements

As we all know, there are certain aspects that prove to be the least important in the assessment of the tablet that we will buy. In this sense, we can say that the camera is one of them, since it is actually possible that only we use for videoconferencing. In short, the quality of the cameras that incorporate tablets can never be compared to the quality offered for digital compact or video digital cameras.

Therefore, if we find a tablet that interests us and has a camera of poor 1.3 megapixel, this is not a subject that should persuade purchase.

Another aspect is the inclusion of a TV tuner, as well as the possibility of playing video in three dimensions, as to enjoy the 3D, we connect the tablet to a TV that has this technology.

Some accessories

When buying a tablet, we should not forget to add to its value the acquisition of a series of accessories which are indispensable to us. One of them, as we have already mentioned above, is buying a micro SD card of at least 8 Gb memory, which currently has a value of around u$s 8, depending on the quality, brand and speed.

Moreover, it is important to mention that most of the tablets, especially 7-inch, do not have USB ports standard, and instead include a mini USB port. In this case, we must also purchase a mini USB to USB adapter to connect, for example, a flash drive to the device. The present value of this accessory is around u$s 4.

Buy a tablet

For those who wish to use the tablet to make drawings, an essential element will be the purchase of a stylus, but not everyone, because if we buy a tablet with capacitive screen, we buy a suitable stylus for this technology, which today has a value of approximately u$s 10.

Of course, being a portable device, it is logical that once we get our hands on the new tablet, we begin to carry the gear to everywhere, so a bag becomes a critical part of your device accessories. We can find simple bags from u$s15, and bags which also includes the keyboard from u$s 40.

With the connecting cables is the same. To cut costs, manufacturers of economic tablets currently almost no added accessories, and adding generally are of poor quality, which does not mean that the tablet is poorly constructed.

This shortcoming in the accessories can be easily solved by replacing the accessories that came in the box of the tablet by others of better quality. Fortunately, on the market we have a wide variety of accessories for tablets and smartphones, including holsters, USB connection cables, headphones and chargers at prices that fit any budget.
