I use it. Its a Unix based architecture so its better than any Windows Box thats for sure. . :-)Something to think about though:Apple sets up a recovery key with vilevault. Its possible that if you loose you password that tech support can get you (or the cops) into the computer. So, dont setup the recovery password key thing when asked. . . or choose some really good personal questions and answers for the key recovery feature so nobody else could guess them and get in later.I even go as far as creating 8 different accounts. On startup, you have to enter the username and password. . and you can't tell which or how many accounts there are.. . . muuuhhhooohhaa. So, I would just hand over the dummy account password to the cops if asked and nobody can see or get into the real account that use.Not a security expert but, I know Unix /Linux/Mac OS well enough to say vile vault works well. Id trust it more than Microsoft disk Encryption feature. I also use remote desktop (Streamer App) between my Mac and my IPhone. So, I can use Tor and all my software on my Mac from the iPhone. So my iPhone is like a little monitor for the mac and I can control and use any feature on my Mac at home. It works anywhere on the road too. . . remote control your Mac from your iPhone. Its great for remote viewing and listing too with a webcam at home. .. check on mail delivery/mailman, traffic on the street etc. . . .record and play later etc. . you can even remote control a Power bar/UPS to power on/off any device that plugs in.Enjoy
