I am looking forward to iCloud Drive (basically bringing back iDisk which I miss terribly) and the answering my phone and hotspot features. So far this is pretty smooth for a first beta release.
heh, yeah.. except for them just dropping it like they did.. that was sort of lame. (but in fairness- they gave clear warnings far in advance as well as free iCloud)
anyway, i currently use dropbox.. something i don't particularly like with dropbox when using it for syncing working files is that it will upload when autosave or a new version is created of the file.. this can potentially happen every 5 minutes and with larger files, it's just a constant uploading/syncing process.. it becomes more of a mess when you have the same file open on two computers at once.. it would be better if the file didn't upload until the user closes the file.. maybe iCloud drive will work better?
another thing with dropbox that pretty much sux is that, even though it's constantly uploading due to versioning changes, the versions don't stick with the file.. i.e.- if you open a file which has run through dropbox, there are no versions attached to it.. (same thing if emailing, usb drive, etc.)
hopefully they've come up with a way to let files going through iCloud drive to maintain their versions if, say, the file is being transferred from the same owner.
