Yeah, I looked into TrueCrypt, but I like the ease of Bitlocker because it's integrated with Windows. It's pretty much invisible if you use the automatic TPM-based setting.
I could also use Dropbox in conjunction with the drive encryption, so it would backup my files while unlocked. From what I understand Dropbox is pretty damn safe. They use all kinds of encryption as well.
Accessing unencrypted files can be as easy as booting a linux distribution from a CD or USB drive. The attacker doesn't even need to take the HDD out of the computer.
Yeah, that's exactly what I don't want. There's just stuff on my computer that's nobody's business but mine. I would hate the fact more that some asshole can crawl through my personal documents than the fact that he stole my hardware.
