I have a kindle. And I wouldn't trade it in for anything. My husband bought it for me 2 years ago for my birthday. I have read more books in the last 2 years then I have in the last 20 years. When he bought mine, it was $249. Mine has Whispernet to download books which means, I can get books anywhere that I am.
The ones they have now for $79 comes with Wi-Fi and has advertisements when the book is "sleeping" we got my husband one of these and he doesn't mind them at all. The only drawback he says is that he can only download books onto it when he is around Wi-fi.
The kindle you are able to change the size of the font which is pretty cool if your visually impaired like me. You can also make the kindle "read" to you in either a man or a womans voice. I have even downloaded a few games. :)
But I think you will enjoy reading a kindle. :)
