To be fair, Android has had a lot of these features for a while. * Calendars and contacts have always been synced with my gmail and across all my android devices since my G1. * Bookmarks are now being synced through the new Chrome for android * On Android you pretty much rely on Google Docs for your document needs, which of course is cloud-based * Photos have been synced with picasa (now part of G+) across all my devices for a while now too * Google music (can't comment on google's book offering, as I haven't really used it yet) Now, I'm not gonna say Google's implementation is better or anything, but a lot of that functionality has been there for so long, it seems at least comprable to apple's offering at this point (if a bit 'fragmented'). I only just got my first iOS device a few weeks ago (an ipad2 from my work), and since it's my only one I can't say I've tested out iCloud fully enough to give an in-depth comparison. I do hope google eventually come out with an API for their cloud storage for android though, as that seems to be the only major thing that's missing. I will say one thing though, I find it quite nice that I can access all the synced data on my Android devices from any browser anywhere, conveniently within the services I already use, and not just from my Androids/personal computers.
