I have the Kindle paper white with the backlit screen and I really enjoy it. I think if you want it mainly for the purpose of reading then stick to an e-reader (like the paper white) and not a tablet (like the Kindle fire).
Beforehand, I couldn't read in bed for very long because the light bothers my dh, but with the paper white I can turn the screen down real low so it doesn't bother him. I can read the Kindle for as long as I can read a real book without it straining my eyes at all, and I usually read for one or two hours at a time.
Amazon has tons of free books, plus if you have a prime account you can borrow many books for free. Our public library also has many books you can borrow for the Kindle, usually newer releases. The paper white can hold over 1,000 books, but in addition to that, any book you buy for Kindle on Amazon is stored in your cloud account so even if you remove it from the device you need never lose the book it is always easily accessible to you. I don't know how many books I have on mine right now, but I have 1,138 MB free and haven't noticed any slowing down of operations yet.
I enjoy being able to instantly click on a word and look it up in the Dictionary, I use that feature a lot.
Ox, with a regular Kindle the screen won't auto rotate, but every device I've seen with that feature has a way to turn it off in the settings, I hope you can get that turned off so you can use yours more.
There are many more lightweight covers available for the e-readers today than when they first came out. Mine is very sleek and all together everything weighs in at just under 11 ounces - heavier than say a Louis L'amour paperback (6 oz) but lighter than the SAS Survival Handbook paperback (29 oz) . The cover has a magnet which automatically turns the Kindle off when it is closed, saving the battery.
It can access the internet if necessary, but that is really cumbersome, but then I wanted it to read books on, not surf the 'net or read emails.
I don't like the advertising that comes with it, but for 20 bucks I can get that removed. When the K goes into sleep mode during Bible study at church and the advertisement is for, say a romance book, complete with a picture of two people in a passionate embrace it can be a little embarrassing, ha!
I do wish that the K would allow a person to organize books into folders on the computer and then sync that with the device, because that can be bothersome to do on the Kindle. If I was more diligent about putting the books into folders immediately after downloading them then I suppose it wouldn't be that bad.
All in all though I have been very satisfied with my Kindle. I started with the Kindle Touch and was upgraded to the Paperwhite for my birthday this year.
