Want the Prime Day deal on the Kindle PaperWhite I fall asleep with every night? You better act fast

Just because I fall asleep every night with the Amazon Kindle Paperwhite Signature Edition does not mean I do not love it. This is my go-to reading device, and before I say more, I should inform you that the Prime Day deal on my favorite ereader is just about to end. You'll want to act fast if you want to sleep with your own e-reader.

I've been reading on Amazon Kindles since the second edition rolled out in 2009. I think I was sold on the gadget when I watched horror master Stephen King read his short story, Ur, on it.

Multiple models (and design changes) later, my Kindle Paperwhite Signature Edition travels the globe with me; it recently accompanied me to California and South Korea in the space of two weeks (on one charge).

Wherever I go, I read and, if it's at night and I'm in bed, I fall asleep with the Kindle Paperwhite resting on my chest. It doesn't judge and just eventually falls asleep on its own (or goes into low-power sleep mode) until someone pulls it off me and puts it on the end table beside the bed.

There are cheaper models than my Signature Edition. The base Kindle is during Prime Day 23% and comes in at just $84. That's a bargain. My signature Edition doubles the storage to 32GB, adds a front ambient light sensor (to auto-adjust the lights that can illuminate the reflective display), and includes wireless charging. On the last bit, I've found that I can drop my Jade Paperwhite on any Qi charger and it will start grabbing juice.

At 28% off, the Kindle Paperwhite Signature Edition is $144.99 (was $199.99) for Prime Day, which ends tonight at midnight. In the UK, it's just £137.74 (down from £189.99). Also, remember you need a Prime subscription to access these deals.

I know, wireless charging is probably a nice-to-have since my Paperwhite Signature Edition lasts for weeks on a charge. Seriously, how many gadgets can you take on a week-long trip without having to charge even once?

The other reason I still love Kindle ereaders is that they are single-purpose devices. When I go on vacation, this is generally the one gadget I'm looking at on the beach and am happy to leave email and social media behind. I read for hours and only occasionally fall asleep (the beach lounge chair is simply not as comfortable as my bed). The 300ppi screen is sharp, fast (20% faster than the last model), and in the sunlight, bright without needing a backlight.

Also, since I can burn through books on the sand, I'm always happy that the 32GB of storage can hold thousands of books and magazines.

One thing I do not worry about when on the beach is a splash of water. The Paperwhite Signature Edition is fully waterproof (I have dropped them in pools to prove this feature works as promised).

Look, you may never fall asleep with your Kindle, but I bet you will have a few sleepless nights if you miss this chance to grab a cheaper one. Happy reads or snoozes (or both).
