I am a urologist in Las Vegas Nevada and I have been in the market for a tablet / phone hybrid that would work as an all around device for the medical assistants in our office. After having priced a lot of different models including ipad minis and the Google Nexus series I was surprised to find a product from Sony that delivered more features and a lower overall cost. The Sony Xperia Z ultra has a 61/2 inch screen so it can be used for viewing pdf files as well as calls and messaging. The device is water proof, comes in three colors that the assistants love ( they all chose purple ) & the android operating system is up to date with lollipop out of the box. With a price point of $220.00 US. it was a steal.
