As Tam mentioned, I had a Kindle Fire before she did -- by about 12 hours: she saw mine, pre-ordered in October, and went to buy one of the less-expensive Amazon readers, assuming the newest (Fire) wouldn't've arrive yet anyway.
It had. She couldn't resist it.
I'm not going to make a rah-rah partisan case for any particular e-reader; I've had hands on the Barnes & Nobles "Nook" and liked it and any of the main contenders offer a similar reading experience. I'd been considering such a device for over a year. The Amazon product's price was the deciding factor.
I like books. My dining room is literally walled with 'em and at any given time or place, I will be carrying something to read, usually a science-fiction paperback. I'm not going to give them up. Print isn't dead to me and it's not going to be. (Among other factors, most of my old-radio library is seriously out of print, despite the very best efforts of Lindsay's Technical Books).
--However, the Kindle is, in any practical sense, a book. My first purchases were Carl Bussjaeger's most recent two books and there was no "adjustment" from paper to page-size screen; reads just the same.
It is not only a book, though, and that's where they got me. In the past four days, I have watched all of the British teleproduction of Terry Pratchett's The Colour Of Magic and made inroads into Hogfather. Both are very much labors (labours?) of love and have outstanding production values; while they do differ from the books, it's very much the Discworld I've come to love. Having those movies right there in my hand, without any herky-jerky download stutters, in crisp image and stereo sound, is a very new experience.
Add in the little Morse-code-trainer game that's getting my code speed back up to something useful (needs work but it doesn't cheat much) and I think I've had $199 in entertainment even before I use it to check my blog -- or yours.
If it sounds like something you'd like, you can buy 'em through the Amazon link at Tam's.
