For the past one year, I've only been reading ebooks and have not bought a single copy of the print book. I read my ebooks on my computer, and there were some issues I had to bear with. For example, the glare of the screen. Reducing the brightness doesn't help as that means the text becomes less readable. My eyes got tired from the hours of reading, and the whites started to develop red 'lines'.
Then there's the non-portability of the ebooks. I no longer had a book with me to read when I'm waiting for someone or for my turn at some place. And not to mention the computer getting hot from being left on for more than 12 hours a day.
Those became issues of the past when I got my Kindle. The Kindle uses the E-Ink technology which makes reading easy on the eyes. It is very light, and now I carry 300 ebooks (the storage capacity is 3500 ebooks) everywhere with me in my handbag so that I'll have a different book to read for different moods. I would not have been able to do that with print copies.
The Kindle lets you look up the definition of a word without leaving the page you're reading, and if you're feeling lazy and just want to close your eyes and let someone read to you, just activate the text-to-speech and let the Kindle read to you.
And if you like to listen to music while you read, all from the same device, just copy the MP3 files into the music folder in the Kindle. The Kindle is wifi enabled, and comes with a browser. I find the browsing experience extremely primitive though.
The Kindle does best what it was designed for --- reading ebooks. It really delivers!
