Bluetooth is only really used on the road since so many states are banning driving-and-talking. I have to have a Bluetooth headset to talk on my phone when I’m driving on an Army post since all posts nationwide ban it, too.
What’s wrong with the Kindle? As long as the book is properly “translated,” it’s a fabulous resource. I did get one book for school that wasn’t translated well, and it was nearly unreadable (no page numbers, no graphics from the book, footnotes dropped in the middle of the page). Thankfully, that kind of experience is an outlier. I also invariably read much faster on a Kindle than a real book, though I’m not sure why.
You don’t want to get me going on Kindle. I have good and substantial non-petty reasons for loathing it, but you’ll be bored, trust me. I know I’m sick of talking about it, and everyone’ll use it no matter what I say. :)
