This means that, if you use this OS on a laptop, you'll be vulnerable to cold-boot attacks, even after you close your lid, unless you configure it to shutdown on lid close. (I.e., if a highly skilled adversary steals your laptop then, even if your laptop lid is closed, they will be able to read your RAM and therefore decrypt your entire hard drive.)
Despite the major security implications, it doesn't sound like a fix will be implemented any time soon. [1]
I don't have any bars on my windows to prevent that.
You need to draw the line somewhere.
I do. And, if I have a choice, I'd rather not have to wonder if this data is in the hands of a stranger after my laptop is stolen.
I'm quite sure if you look at your average thief and multiply these to chances together that's less than one in a million chance to happen. Assuming you're not some high profile person where the right person is out to get you and knows which OS you use, and knows how to steal from you.
