Many users might have a bit of a learning curve with Tails, especially if they're not familiar with the software included with it. You'll have to take extra steps to set up good email and file encryption, and anyone you exchange emails or encrypted files with will also have to work with some special configurations.
Fortunately, the Tails documentation is quite good; you can read it online, and the local copy that comes with Tails is conveniently bookmarked in Iceweasel. And if you're concerned about privacy, it will be worth it.
