Chromebooks, the first Google Chrome OS computers

After months of hearing about Chrome OS ---- The operating system from Google. The search engine company finally moves on and breaks into the notebook market with a pioneering and risky bet. The Chromebook inaugurate a new concept of teams that use the Internet as the basis for its operation.
The first batch of machines with Chrome OS consists of the Samsung Chromebook Series 5 and Acer ZGB Chromebook. Except for the size of the screen, both devices share almost all specifications and are a good starting point to familiarize themselves with the proposed Google.

Operating system, Chrome OS is minimal. The storage space Chromebook is virtually nonexistent. Only 16 GB of SSD memory in which drivers are installed and the software necessary to operate the equipment. All documents are stored in the cloud via services such as Google Docs, YouTube or Gmail. In fact, this solution ignores the desktop, with the main system screen web browser, where you will find access to most used applications, settings and other online services.
Obviously, Chrome OS software is an extremely lightweight, combined with the processor fitted to Chromebook. Guarantees a dramatic improvement in the time of startup. Instead, they need an Internet connection can be a weakness in areas where no WiFi areas and 3G coverage is limited. In our view, the main difficulties will have to overcome. Chromebook are not technical, but changing the mentality of users.

Connections to a minimum

The vocation of always being connected to the Internet minimizes the need for physical connections, which are reduced to a pair of USB ports and memory card reader. Only the model Acer goes with a HDMI port that allows connection to a TV. As for wireless connections, the base is Standard WiFi 802.11 b / g / n.

The 3G is an extra, but given the need to always be on-line, its use is almost mandatory if you want to take full advantage. Although it is a bit anachronistic, we miss the presence of a network port Ethernet.

Although there are many hotels and buildings that rely on the old but reliable wiring. Moreover, the use of 3G data abroad is practically unfeasible because of its high tariffs, which is a serious problem in bringing the Chromebook to another country.

Always ready for action

One of the best points of the Chromebook is its rapid response capability. The operating system boots in under 10 seconds. Also, both teams are able to go from sleep almost instantly.
As for autonomy, the model Samsung has a more powerful battery, which gives eight hours, and average nominal autonomy. The Acer Chromebok ZGB, Slightly smaller, reaching only six hours. Remains to be seen, however, how it affects the continued use of WiFi and 3G connections to this performance.

Applications in the Cloud

From the home page Chrome OS you access the main applications. Most of them are associated with Google services. The office documents such as tables, texts and databases, reside in Google Docs. YouTube is the main video player and team Picasa is given as an organizer of images online.

Gmail -- Besides serving as a mail client, brings together the functions of videoconferencing and chat through Google Talk. In the future more applications will come from Google and others. The idea is to create a market around Chrome I similar to that which already exists in Android.

For companies

During the conference Google I / O in which we have presented the Chromebooks. The firm has advanced to the console marketed with a hosted web administrator and 24x7x365 support from $ 28 per user per month for businesses and $ 20 for schools. The aim is that from this single console can be controlled accounts, applications and devices.

Since December, many companies, IT administrators and teachers are part of the pilot program to test the Chromebook. Their experience is that the battery life and 3G helps you work longer and in more places, its fast and reliable start to focus on teaching, and administration is simplified, reducing safety concerns too.

Processor inside

Both Chromebooks move through a process Intel Atom N570 dual core 1.66 GHz chip which is a low power along and with 2 Gbytes of DDR3 RAM, which offers more power required to run a lightweight operating system and applications that greater weight is on servers km away. If there can be a bottleneck in performance, it will come from the Internet.

Single chassis weighing netbook

Both Samsung Series 5 as Acer ZGB does not boast of great fanfare in design. The dimensions of both units are standard in the world of laptops. The weight, however, is lower than any traditional computer, and which dispenses with some components like the hard drive of a lifetime or optical drive. And is that such computers are designed for those users who live on the Web.

Padphone have to wait for Ice Cream Sandwich

Asus catches our eyes with a creative idea, they release their Padphone which merge mobile phone and tablet pc last month, this is a creative idea for portable device. However, have you found that Padphone is just a Dummy? If you are sharp-eyed, you will notice that Padphone stopped in the main interface and never change when you watch the video or the picture of Padphone. Therefore, it should be a Dummy.

According Asus's design, smartphone is the main body of Padphone. When it works on smartphone, the user interface is mobile phone. When smartphone docks inside the tablet, the user interface is tablet pc in the bigger screen. Smartphone is the core, tablet pc is just a screen with speaker, I/O connector and battery, tablet pc is without CPU, so smartphone have to play the role of CPU. Considering the current Android OS system, Asus have to install two different version in the smartphone -- Android 2.3 and 3.0. However, as we all know, 3.0 Honeycomb couldn't work with smartphone.


However, Asus deny above opinion. Benson Lin said, actually, this device will be released until Christmas and it will come with the latest Android OS. But they don't recognize Padphone have to wait until Google develop Ice Cream Sandwich.

Next version of Android -- Ice Cream Sandwich  will integrate Honeycomb and Gingerbread, therefore, will integrate smartphone and tablet pc. It has two different user interface, which is consistent with Asus Padphone design concepts, one system with two experience.
If Asus want to launch the real Padphone (no Dummy), it all depends on Google.

How to choose an Android Tablet PC

Article from: http://www.dootar.com/

Android Tablet PC heat up nowadays. More than hundreds of Android Tablet PC on the market. Which one is the best for you? I can give you some suggestion.

What will you do with an Android Tablet?

This question is very important. It all depends on yourself. There are many application for Android Tablet, so it can complete many task. The main functions of Android Tablet are: surf internet with WIFI or 3G (Facebook, Twitter, Youtube, Skype, email, etc.), watch video and listen music, reading ebook and documents and play games. Almost all the Android Tablet have above functions.

Main specification

1. Operation system

Different version of operation system can support different function. However, many application require the system should be above Android 2.1. Therefore, at present Android 2.1 is minimum requirement. My suggestion is Android 2.2, because it can support Adobe Flash, you can watch video on a normal webpage. Android 2.3 does not have big difference with 2.2. Android 3.0 has been released, but in my opinion, it takes time to test and not stable as 2.2. (I am writing this article on April, 2011)

2. Sceen Size

7 inch, 8 inch, 9.7 inch, 10 inch -- small size is lighter but image is small when you watch video or webpage. Big size is heavier. It depends on yourself.

3. CPU

CPU is the most important. It decides the reflection and the price of a Tablet PC. The CPU with cortex A8 or A9 is the best at present, such as Freescale and Telechips. CPU VIA is the cheapest one. The difference of CPU can have more than US$50 difference of price. My suggestion is to take CPU with cortex A8 or A9, it works much faster.

4. RAM

RAM is another important element which decides the reflection of Tablet PC. The bigger RAM is the better reflection of Tablet PC. At this moment, 512MB is the most popular size on the market.

5. Touch screen

Resistive touch panel is more accurate when you touch a point. However, more and more manufacturer use capacitive touch panel because it is faster (no delay when you type on the keyboard) and support multi-touch. Therefore, capacitive touch panel is the better choice.

CPU, RAM and Touch screen decides the reflection of a Tablet PC. They are the most important specification when you are looking for a Tablet.

6. ROM

ROM is the memory. It is like a hard disk. So the bigger the better. But this is not very important, because you can extend the memory capacity with a TF card.

7. Camera

The camera is almost useless unless the Tablet PC is with Android 3.0 operation system (Android 3.0 supports video talk).

Main function

1. G-sensor

G-sensor is the great creation from Apple company. It becomes the basic function for all Tablet PC. With this function, you can not only rotate the picture or menu, but also play G-sensor games such as racing car etc.

2. Adobe Flash

Tablet PC which support Adobe Flash can enable you watch video on www webpage. I think you don't wanna buy a Tablet PC and still read small webpage like in a mobile phone.

3. Multi-touch

Multi-touch is another interesting function. With this function, you can enlarge a picture or webpage or documents by your two finger. It is also another basic function for a Tablet PC.

In the end, I personnally recommend two models of Android Tablet PC for your reference -- 70S1 and 10A9. 70S1 is 7 inch Android 2.2 Tablet PC with CPU cortex A8. 10A9 is 10 inch Android 2.2 Tablet PC with CPU cortex A9.  They are the best chinese Android Tablet PC at present.

The battery of T2 is 6000mAh. It can work around 3 hours when you turn on the WIFI and around 5 hours when you turn it off. The capacity of battery is normal. It is enough if you play or work with Android Tablet outside.

Conclusion
T2 must be the king of chinese Android Tablet PC. Best CPU, best RAM, best touchn panel and best design. T2 just shows us what an Android Tablet PC can be. It designs for OEM. You can select the functions you need in T2 and delete the functions you don't need. Because if you need all the functions, the cost is very high.

The creative highlight for 10A9 is the presinstalled 3D shell. When you start the Tablet PC, you can view the Weather Report, News and Google search by sliding the screen. The Programmes menu is in 3D too. If you start the music player on the desktop, the music player is also in 3D. That is very interesting.
