I own a Clara HD. I don’t find it sluggish (quite snappy unless it’s trying to render badly formed PDFs, there is no ghosting after 3 years of regular use and my inputs are never wrong, but I have been using Koreader on it for all but month 1. It sounds like your screen is polling too slow if you’re getting misinputs, or something else similar. Not an amazon product and doesn’t give me ads either.
Oh DSL, I remember asking other kids in middle school how they knew Angelina Jolie had Damn Small Linux as an OS. Learned a lot that day.
