Seconded. I got one of these and was surprised at how much I love it. The input latency is unnoticeable. I intentionally don't connect my email, calendar, or anything interruptible to it and it is a wonderful notepad, reader, etc.
Not connecting email, calendar, social media, or anything else that produces notifications is the best thing I ever did with a tablet.
Email, social media, etc. is a productivity black hole due to notifications. At first I tried disabling notifications but it isn't enough. I had to remove the accounts as I just can't be trusted to not check manually.
I used to hate my iPad because I never got anything done on it but since removing all that crap it is a fantastic device for when you want to focus on one task and not be distracted.
