No, I don't use a bigger screen. I love reading on the smaller screen of my phone. Someone offered to give me a Kindle but I turned it down. I prefer the backlit screen (I can read in bed without a lamp...I just turn my phone's brightness setting all the way down so it's comfortable for my eyes) and the smaller, more lightweight device.

I'm not a fan of the grayness of the screen of ereaders like the kindle. I like having the option to change the color of the page and text. With the kindle iphone app I even have the option to have a black screen with white writing...really nice for reading in a dark room.

I love that I can bookmark things, highlight things, add notes...and easily find what I'm looking for later on. And I love that ebooks are cheaper. I've been known to browse bookstores (I still prefer shopping when I can thumb through a book) and then buy the books I like on my phone.

I don't spend my workday on the computer (a small part of it but most of the time I'm sewing) so my eyes never complain.
