So I've been using Aperture since 1.0 but am seriously contemplating jumping to Lightroom given Apple's lack of support recently on not just Aperture but all their software. From what I've read, the functionality seems pretty similar so that shouldn't be a problem. One thing I could see myself missing though is the integration of online printing. I've been quite pleased with the results whenever I've gotten photos through Apple, though the last time it took over a month to receive my order and I had to print them elsewhere. The photo books are great though. I see that there's a Blurb plug-in for Lightroom. I've gotten a book from Blurb before, but the quality just wasn't the same as through Apple. So the question is, what online printing services do others use that give a good balance between quality and cost for books, prints, whatever?
