Was there a thread on here or some article online about just this very topic of the frailty of thief proofing your stuff, that if they really wanted to get your stuff they'll just succeed and there is really nothing anyone can do about it? So you get it back after what a year or more because tax payers money went to officials to trace its whereabouts ? It comes back in rough condition or gutted. It may not even come back because some sucker purchased it on some eebayy like store for near nothing for it and didn't think anything about the major scratch marks or dents etc?
If you got something to hide or really important legal and financial things that are sensitive, work or school related what ever, don't keep that stuff on your phone or computer. Of if you do have a lot of sensitive privacy stuff, just know that you've waived your privacy the moment you decided to digitize your life. There is NO SUCH thing now of privacy unless you keep it in your own head and no one else knows about it but you. Once it is in digital format, the sky is the limit as to what these crooks can and will do with all of your information.
Security is a marketing gimmick remember that. You are your best privacy protection, who ever you don't want to get in on your stuff wont because you made it so, no program, no app and no lock will keep anyone who really wants in and KNOWS HOW to get in no matter what, will secure your precious private information etc.
Rest easy that the best protection is your common sense. It doesn't cost anything and it is lighter than an empty molecule.
