Sony is launching its new tablet Sony Xperia Z, this announcement has done in MWC (Mobile World Congress) 2013 recently.

It is very light than you think if you are holding this and not watching it then you will think to hold a 7-inch device, isn't it shocking and amazing. All the tablets should be lighter like this.

You wouldn't believe that Xperia Z is just 0.27 inches thick and 1.9 pounds weight and it is 27 % thinner and 24 % lighter than Apple's generation 4 iPad.

It has displayed for the first time in Mobile World congress.

Xperia Z has 1.5 GHz quad core processor, 2 GB RAM and a full HD screen of 1920*1080p resolution.

The major quality of Xperia Z is: it is water proof, you wouldn't believe? Yes, it is.

However, in international market it does not get any specific attention. May be it is because of last year's model which has Snapdragon s4 chipset from Qualcomm and the pixel of model wasn't much higher. But, apart from this Xperia Z is suitable for 2013.

You can't think that its price will be less after seeing its weight and thinness and it is not that this device feels like a toy because it is lighter and thinner but still it is a premium tablet.

It has also some drawbacks rather is has a lot of plus points too. Its main drawback is its interface as compare to the Google's UI and Xperia Z is annoyingly pushes many of Sony's apps and services.

Another drawback is that it doesn't support Andriod 4.1 but Sony has announced to launch its 4.2 later, It can be this week, this month or later than this.

Its cost is $499 with 16 GB model $599 with 32 GB model. It seems very expensive like Nexus 10 and iPad. There are rumors in the international market that Apple and Google will also launch their updated and latest tablets later this layer and off course before table Z successor.

I must say at the end that, Xperia Z will be the worth watching device when it will come for sale in market. I would say that Xperia Z is the most impressive device in Mobile World Congress and i am very excited to hold it and use it when it will come.
