I have the similar kind of problem. I am planning to buy a tablet to read research articles published in PDF. I have also narrowed down the choice to Nexus 10 and iPad 4. My problem is I need a system which can display two column pages containing text and some graphics. I do not wish to read in the wide screen mode. Now, based on the pictures I saw on YouTube, it seems iPad has a better width than Nexus, which has an elongated screen for horizontal watching. This, i assume will make reading two column PDF documents somewhat better to read in iPad 4. However, iPad will tie me up with Apple store and I do not want to pay for even minor apps, whereas I have a large collection of free apps in Nexus.
I could not compare them side by side as nexus 10 is not available in India and is available only as mail order delivery. However, YouTube videos show that in the vertical position, the keyboard width is somewhat smaller in Nexus 10 but better in iPad.
Then again, my wife has an Android mobile and I use old fashioned mobiles and I wish to have the pure android experience (I believe within the next 2 years, the app quality and quantity and the android experience will far surpass iOS!) of Nexus 10. But the priority is reading two column PDF pages in vertical position.
Confused!!
Anyone had such experience? Can anybody post a side by side screenshot of Nexus 10 and iPad with two column PDF docs opened?
