Thanks to a post over on Twitter, I found this article. I hadn’t realized it but apparently Kindles and Sony readers both have temperature limitations. If you let a Kindle get below 40 degrees (Fahrenheit), you run the risk of the eInk screen dying. Apparently the Sony Reader is similar.

NOW I find this out – I took my Sony Reader with me the other night when I was waiting to meet Curly. It was definitely below 40 degrees Fahrenheit, more like closer to 0. I wasn’t running the car the whole time, and I’m not sure I did let it get below zero, but I’d brought a quilt along with me to keep me warm so I wouldn’t have to keep running the car/wasting gas/polluting the environment. I guess I must have kept it warm enough because my Reader is still working fine.

According to Mr. Bilmes’ blog, just carrying it around in your purse or your backpack as you’re waiting for the bus can cause the machines to malfunction. And heaven forbid you leave it in the car. Not good to find out if you live in Canada where six months of the year we’re below 30, let alone 40 F.

    Gotta love this info after the fact. 🙂 At least yours isn’t damaged.

    oh yuck! I’m glad yours didn’t freeze.

    I’ve learned to check for that sort of thing though… of course, in my town, not for cold, but for heat. Lots of products aren’t supposed to get over 100 degrees or so … umm… around here that’s a problem. *sigh*

    Sue – that’s a good point, so I checked its upper limits. 95. So you’d have to be careful not to put yours in a backpack and take it with you when you’re camping overnight somewhere.
