I have had my kindle about a year now and I love it - it's brilliant for one handed reading, and superbly easy to read in bright sunlight, unlike my notebook which is useless at that. It goes with me to every Dr/hosp. appt. and anywhere I might have to sit around and wait.
When I am tired, I let it read to me, though it sometimes says a strange word as it's reading phonetically, or with unfamiliar emphasis on a particular syllable - makes me giggle.
I have just downloaded 900 free books my SIL found for me, so that will keep me out of mischief for a while. When I have read a book, I archive it back to Amazon (they are still mine to read as many times as I want, just using their memory, not mine)
I still like books, but most of mine are non fiction, i.e. craft books, and I don't think a kindle is really good for that because of the diagrams & Pics.
