I'm a few chapter's into Hartl's book now. I really appreciate how it explains most things on a few different levels, i.e. both the concrete and theoretical workings of a piece of code. I don't understand much yet, but instead of frustration (I've had a few programming books whose learning curves have turned vertical), I feel excitement.
If the start of the book is any indicator, it's a great resource.
I'll second this... I just used Hartl's book to jumpstart my Rails knowledge and I found it to be an excellent resource.

Part of the reason I recommend it to people is that it includes a very good and gentle introduction to TDD or (if you don't buy agile) unit testing in general.
