I agree, but god damn, I am jealous. I have two small children and I've finished one book this year. (Coders at Work by Peter Siebel, I highly recommend it.)

My wife reads 10x faster than I do but completely eschews the kind of reading I like (viz, literature). But of course, now that, y'know, she has kids too, her overall reading speed is strangely reduced as well.

Anyway, at a first glance I found the line coloring helpful.
