I have the previous DX model, and use it extensively for technical and personal reading. It's not perfect, but it's convenient, light, and very easy on the eyes. Since I'm in front of screens all day, I greatly prefer it to a tablet, at least until the Pixel Qi screens arrive in force. I do buy a few books via Amazon, but mostly I buy PDFs so I can read them on my dev box, phone, etc. as needed. The PDF reader isn't perfect, but it's good enough. So yes, in my opinion the benefits outweigh the drawbacks. I'd suggest you get a slip case for it, though, otherwise you'll always worry about it when you carry it around. (That goes for and tablet format electronics, though.)
