Books in their new Avatar

Yesterday I was reading an article on The New York Times.It discusses about how technological evolutions are changing the habits of reading books.The author was in a flight.When the flight was going to land an announcement  was heard requesting the the passengers to put down their books.Few years ago everyone would have been confused by this announcement.But not today.Everybody obediently switched off their kindles and ipads.This shows how widespread is the use of ebook reading devices nowadays.Gradually these are becoming part of our day to day life.May be in few years from now everybody will own a 6" library at his disposal!In recent past widespread use of mobile electronic gadgets are promoting this new trends of reading.There are different categories of devices.Some are dedicated ebook reader like Amazon kindle,Sony ebook reader.These devices are for reading books only in black letters on white background like conventional books.they dont support coloured text .Amazon and Sony argues that the book reader are not concerned about colour.Dedicated ebook reader have e-ink technology which makes the  text as good as text in a conventional book.Reading book on an Amazon kindle will not strain your eyes unlike reading book on a palmtop or on a laptop or smartphone.Some people argues that as habit of reading colour text with photos and videos is growing via internet,there are people who would like to read color text with photos on their mobile devices.The next two types of devices I will discuss are this type. Nook color by Burns and Noble  is having color text with some auxiliary features.These additional features let you do things beyond reading.The third type of devices are the iconic ipad and its "cheap" imitations like samsung Galaxy.Ipad is more than an ebook reader.It is a full fledged computer.So if you have ipad with you you dont need to carry ur ebook reader additionally.Though it does not have the advantages of e-ink technology as mentioned above.Competition is fierce among these three type of devices but ultimately people will decide in which form they will read book in future.
