My impression is that the Eclipse UI is a bit unintuitive. But it's simple to use (and powerful) once you know how.
Maybe it's just me, but I learn best through example. I need to learn how to do something before I can get too deep into the why. I'm also admittedly lazy, otherwise I wouldn't still be programming after all these years.
Anyway, since I don't work with anybody who already knows how to use Eclipse, I bought the book "Eclipse In Action" from Manning Press and found it to be worth every penny in the time and aggravation it has spared me.
I wasn't previously aware of Mr. Pluta's "Step by Step book, but it seems that it may complement the material in the one I already have, so I might buy this one too. (Assuming I don't get lucky and win it.)
