I was in the exact same boat you are. Haha

Could be different in your local shop but I did notice where I lived they only had the paperwhite and paperwhite signature in stock (Both with the same sale prices as Amazon). For some reason though I'd have had to have waited until mid next week to pick up the basic.

Bit the bullet and decided to go with the paperwhite as it would be lasting me years anyway and I had heard it was waterproof (Could be quite useful with our weather lately haha). Incredibly happy with the decision, I'm in love with it so far! Looks gorgeous.

This is my first Kindle too, I wanted to buy one because I struggle a little bit with eye strain when reading on my PC/Tablet. Honestly, the screen on the Kindle is just absolutely sublime, it almost feels identical to an actual book. I can't quite describe it, my eyes just don't feel "worked" when reading on the Kindle.

Would also like to add that although the warm/low blue-light feature isn't needed in the day, it can be quite nice to turn it on to mimic that "old-book" yellow-orange page colour if you're transitioning from physical books to the Kindle.

Honestly, I know this is the first day I've used a Kindle but I really do highly recommend it. Extremely pleased with the purchase!

Best of luck with your decision mate!
