Why keep a diary when there are blogs? Oh yeah, we do remember that some people pen things down in a rather therapeutic manner, and do not want those thoughts to be made privy to everyone else – even strangers. Why not settle for the Secret Diary instead? This digital diary is actually a removable USB flash drive, complete with additional fun features that requires a PIN for further access. All you need to do is plug it into a computer to type down your thoughts, and when you’re done, remove it. Just in case you misplace or forget your PIN, the optional PIN replacement assistance service helps you access your past thoughts. No idea on whether anyone would want to fork out $99 for this piece of digital secrecy though, since a password protected file would do equally well here.
