It's been almost half a year since Apple last updated its popular iBooks e-book reading app. While this update doesn't introduce anything dramatically new, it does improve compatibility with iOS and iCloud, according to the changelog.
I could wax poetics here on about the features that iBooks has (or lacks) compared to other e-book reading software, but possibly the most important factor in determining its worth is whether you want to read e-books tied into Apple's iBook ecosystem.
iPad and iPhone users can give the update a try by following
