Since I'm not sure how else to answer this, I'll just describe what I need it for.
I like taking notes that I consider private, I'm a writer who doesn't want his material to be seen until I feel that it's finished (I'm sure you can relate being a publisher here). I also have a project that I'm working on that I will turn into a business in the future. That and some copies of confidential documents that would just cause me a lot problems, should those snoopy relatives see them. I know, it's unusual, but that's the kinda people I've to deal with.
I need to protect it from relatives who are extremely snoopy and happen to have a key to my apartment, one of them is very tech savvy and could be relatively determined to get his hands on the data. I also live in a country with fluctuating governmental situation, and recently heard of quite a few unsolicited searches based on someone "tipping" them that you may be a spy, or even based on something on your social network that could be considered unpatriotic. So, in case of that, I'd like my information to be protected, not because it would cause me problems with the government (nothing illegal going on), but because I value my privacy, and whatever I do, is mine to share.
In other words, it's not NSA-class decryption threat we're talking about, but definitely higher than a kid trying to open a password-protected doc file.
Hope that answers your question.
