I have PilotFAR and PilotAIM. I'd say they're both worthwhile. Easily searchable and much nicer to deal with than the physical book. The figures in PilotAIM are fairly low-res, but good enough.

I also used PilotPrep from the same developers when I was studying for my private pilot written, and that was a great boon. Any time I had a minute or two spare I could fire up the iPhone and test myself on a few questions. I'd recommend it to anyone studying for the written.
