I have had a DX Graphite for a couple of months and I am very glad I bought it. Firstly the screen is a decent size and I can read technical PDFs without a problem, second it's an e-ink screen and I can easily read it in direct sunlight unlike with LCD based tablets and it cuts out the eyestrain too. The only big drawback is the lack of colour, if you're reading about data visualization or any other subject that needs colour illustrations I wouldn't recommend it, personally I have an old Samsung Q1 Ultra for that, which is more than adequate, I'm waiting for devices with Marisol displays to come out before I upgrade.
