Re: “unlike tablets, Kindle is designed just for reading”
"meaning it's more cost-effective to buy a bloody tablet and install the Kindle app on it..."
Go on then, read for an hour on a Ipad, put it away, start up again 8 hours later, put away for a day, pick up, read, put away and repeat for 3 weeks. Without charge, without having to wait for it to power up and shut down.
I challenge you.
