I got about half way through downloading Lion, for the second time, got cold feet, and cancelled the download. It occurred because of the lengthy list of things iCloud does not do when compared to the soon-to-be defunct MobileMe. They actually tell you as you're going through the process of transferring services. It's cool they did that so people wouldn't freak out in the aftermath. I think Apple will probably integrate all those old features as iCloud gets stable but my last experience with OSX Lion was less than stellar.
You need OSX Lion for iCloud to sync everything between Apple's desktop and mobile platforms.
I like the idea of everything being integrated, but it feels like a distinct shift from being a service professionals would use to one tailored for consumers. With Apple's increasing market share, I guess I shouldn't be surprised. I can still be disappointed.
I went ahead and put iOS 5 on my iPad because I hadn't yet given it a chance. While the new features are provocative, the walls around the garden have gotten higher. There are yet more applications shipping with the device you can't get rid of if you don't want them. They've even got one you can't hide in a folder because it basically is a folder.
iOS 5 signals a departure. Instead of holding a mobile PC in my hands, I'm saddled with a content delivery device I don't fully control. Maybe I was deluding myself before, but my eyes are wide open now. Looking at what Amazon intends to do with Android and what Apple has now done with iOS, I'm hoping the Windows 8 Tablet devices take a higher road.
