I want to download the digital version of the Real Book (at least 1 of the 5 volumes available), which is available on both iBooks & on Amazon, for which I would use the Kindle app for iPad to read it on. Anybody downloaded this on their iPad? Which app (iBooks or Kindle app for iOS) would be better? Do either of them allow exporting pages as PDFs, &/or printing pages? Thx, MCJazzer
