What do you prefer for reading a tablet or an ordinary paper book?

It depends on the situation, paper book is suitable for eyes' health and for reading a full book. E-book is suitable for reading on the go and for searching specific clause in the book rather than reading it all.

Would prefer Ordinary Book with a table and chair not on bed...

For me E-book is better cause I can read it any where & any time (in the dark - metro - bed etc..). also I don't worry about forgetting where I stopped or the weight of a big book or about my children making it a coloring book :). Besides I may have a whole library in my tablet to choose from.

If available then paper book. In this fast life we are ignoring our health issues. After8 - hrs of job on computer it is not good to read book or news via electronic media.  Try to buy a paper book or newspaper.

i prefer paper books, the light coming out from the screen is really bad. regardless how much you try to adjust it.

i could spent three or four hours reading, imagine staring in a screen for that long.

I prefer Reading Tablet because of space consumption , Paper saving and future technology integration. I believe one day humans will be able to evolve in to class1 Civilization and start colonies in space for survival. It is essential to be integrated with technology for that advancement. 

I prefer to read hard copy (Paper Book) rather than soft copy (E-book).

Hard Copy over ebook anytime. Although ebook does give you the opportunity to read anywhere of your favorite digital media.

My preference is a hard copy only. Also depends upon the availability and location where I'm also important.

reading a book for sure ... I think we should give every thing it's proper value ... so reading a tablet in my point of view decreasing in value the BOOK .... that's all :)
