I bought a Kindle at Christmas and LOVE it! I'm a paper kind of gal and really resisted getting one, but felt it was time. I'm doing SO much more reading now that I have one. For me, the big plus is being able to adjust the font size. No more squinting at tiny text. I can make it big so it's easy to read at night when my vision is at its worst. It's also really portable so I can pop it into my purse to read while the kids are at gym practice.
I have little patience for figuring out tech gadgets and even I could get the thing up and running and use it right away. The battery life is really, really good, too. I've been reading a few nights a week since Christmas and it only last week needed the battery recharged.
