An avid consumer of Dropbox services for trivial files, I was truly extatic with the announcement of iCloud. But in my opinion, Apple didn't get it right just now. I would trust Apple for storing my sensitive, highly confidential info (I do not trust Dropbox as their core-business is files storage and don't know how much they do data-mining on hosted files) but as of now, they are not offering me a way to do it. iWork: I love the ability to save from iOS to iCloud but to then work from iWork on Mac OS is clunky: have to download my files from iCloud website, edit them and then publish them to iCloud manually again. If a file has not been edited on iOS device, I can't download it back. At the moment, I only use it to start documents while on the go in Pages, when on my desktop machine, I download the file and move it to Dropbox. Other files: As there's no possibility to upload any files other than those from iWork, so far, it is not a Dropbox alternative. I would like iCloud to grow into a "sync folder" type of service and am very surprised it doesn't do that. IMAP mails is nothing new, Calendar sync neither. I really don't see where iCloud innovates from already long-time existing services. When Steve Jobs antagonized the Dropbox guys after they refused to sell and telling them they are a mere feature, all I can say is that Apple failed to provide that feature.
