Does a device like this have faster screen update rates or is more responsive to inputs than e readers like the Kindle?

I only ask because I had to stop using the Kindle and go back to paperback, and I am by no means a purist for these things. I just found the delays in everything so bad to use that I was actually avoiding reading just because I was avoiding using the device.

I'm hoping to revisit e readers in a few years to see if things have improved on that front.
