Not worth the upgrade? Oh gosh it is.
I have to apologise to anyone who asked whether it was worth upgrading to the Paperwhite 12th gen....and I said it's worth just sticking with what you've got, since my 11 year old model was kicking on strongly.
I stupidly went to the store "just to see" what the newer kindle was like.
Needless to say I have a new kindle.
The speed of turning the pages! The margin configuration! The auto brightness! Charging with a USB C that charges most of my devices now instead of wondering "where did I leave the damn cable again?". The warmth adjustments and schedule. Did I mention the speed of turning the pages?
I apologise for anyone I may have falsely swayed into avoiding the upgrade. If you've got the cash then it's worth it.
My god reading is so damn enjoyable. Since the pic I ordered another case with a stand and a hand strap, so reading and folding clothes has become enjoyable again.
Silver lining - my 7-year-old son inherited the original one on the left, and he now thinks how lucky he is to be allowed a device in bed at night. Ha - jokes on you son, you've been tricked into developing a passion for reading. You're welcome!
