I have to agree wholeheartedly with this piece by Chris Bowler. I'm using iCloud a lot more than I thought I would because it's just so damn easy, and the syncing just works. And, like Chris, I was astonished by how easy it was to set up my new laptop using iCloud, Dropbox, and Evernote… and I didn't even use Migration Assistant.
The (Un)Obviousness of iCloud: "And so it has gone with iCloud overall. I never really set out to use it to its fullness, but it has become integral to my computing experience. It should have been an obvious transition, but instead it was subtle. This past year came with migrations to two new laptops. The ease of setting up each blew me away both times."
