I have to say too this has been an epic fail on the same scale as Blackberry's Playbook with mising email/calendar/contact functionality and HP's Touchpad. And we've seen what happened to them.
I'm sure that iCloud works great for consumption device/usage purposes. And it works with Windows Vista/7/8 Beta! But it doesn't even work with Snow Leopard! Sorry, but I have to upgrade to Lion and pay for new versions of all my software because they aren't Lion compatible and the app developers won't patch to Lion or can't? So there's money to upgrade versions, upgrade to a virtual machine to keep Snow Leopard running in a sandbox with orphaned programs so data/capability isn't lost, etc.
Admittedly I'm both a professional/business and consumer user...tha's iMac, Mac Mini, MacBook Pro, MacBook Air, iPhone 4, iPhone 3GS, and iPad 2 between family and business. Professiona/productivityl work is on the Mac, consumption/data viewing/connectivity/coordination is on iOS. So looking at the capabilities:
- iCloud offers email/contact/calendar syncing. I can do that fine with Gmail/Google right now, much better than Mobile Me ever could. So while that might be useful, I need more reason to disrupt my existing connections and services and switch such as stability and additional functionality of bringing all my services to one provider. And Gmail isn't limited to Lion only, it works on iOS all versions and Snow Leopard.
- iCloud offers note and reminder syncing. But it only works with iOS 5 and Lion. I can do that now with Google, Evernote, and many other services and they work across all devices.
- iCloud offers music and related media syncing. But I can do the same thing now across all devices using iTunes without having to upgrade to Lion or iOS 5.
- iCloud offers a crippled version of iDisk document and important file syncing. It removes any sort of file sharing domain. And requires update to Lion. I can do that with DropBox in a disk drive-like environment with no loss of functionality to iOS, Snow Leopard, Lion, or Windows devices. And if I want secure, I can just deposit the entire file structure in an encrypted file as a drive and use that off DropBox and just drag things I want for iOS out of that on Mac before hitting the road.
The problem I see from the above analysis is iCloud has some great ideas. But it has made itself a niche product rather than a relatively all-encompassing service (which they could have easily done with a little forethought...it doesn't have to do everything, but it has to do the RIGHT things and do them WELL to win). And without the later, as you can see from my above analysis, there is no impetus to switch. I was planning to move the remaining machines to Lion, update our iOS devices to 5, and invest in a 4S iPhone primarily because iCloud originally looked like it would allow me to bring all my needs under one service as both professional (a HUGE Mac segment) and consumer. Now instead I am abandoning any upgrade plans as the new capabilities aren't compelling enough at the moment to invest money and lost time to learning new functionality to, and instead will move to even further third party services to improve capabilities independent of how Apple implements itself. Again, sounds like the Blackberry Playbook story all over again except this time Apple is the one behind the curve and likely to fail if so many of us will not bother using this new service no matter what its price, free or otherwise.
I too am hoping they get the idea and improve things across the spectrum. But its six months in and Playbook stil has no email/calendar/contacts. If Apple is thinking "we'll add this in a year or two", they will be too late to the game as the HP Touchpad was. iCloud will have become a primarily consumer/niche product much like AppleTV by that time. This is a critical junction between their consumer and professional segments (which as with me actually overlap, are not separate)...this requires a fix in a month, not a year, if they want a market "win" instead of "thud".
