I mostly just use it for image hosting for forums or to quickly give something to a friend, which it's just fine for.
Also, before someone comes in blaming the whole cloud thing again, it's not the fault of "cloud". It's a fault of a lying company. If your bank told you that your money would be safe with armed guards and you would not be responsible for someone robbing them, but it turns out the bank stored all their money in an insecure normal office and someone casually broke in and took the money, you would blame that one bank, not the whole banking system.
