I use free (TrueCrypt) for containers and paid (BestCrypt Volume Encryption) for system/non-system/external drives/flash drives encryption.
I'm too pure unencrypted. Once we had some fuss that our letters could be read countrywide for security measures. I said "And what? I don't care. Though it's unpleasant."
Even my external HDs and flash disks, phone numbers and driver plates are not encrypted! What a horror!
I have a partition which is encrypted. All my sensitive stuff are in there. I also have a flash drive which is of the same nature --files that are sensitive that I need to bring to office. Mostly when I encrypt files it's in a container in a separate partition drive which I backup prior encrypting it. An changes I do that container I manually backup first. I am a fan of Hushmail and I use it for sensisitve emails to office, etc. I use TrueCrypt and TheVault.
I have absolutely nothing incriminating or of value stored on my computer so why would i wish to encrypt it.? If i were a government scientist or something with top secret data stored on my computer then i could understand the need for encryption. Even if i were in possession of such data surely i would not be stupid enough to store it on the computer in the first place.! I think people should evaluate as to whether the data on their computers are really something a thief would want or need.
If I do want to save my data, I'll encrypt it and transfer it over to my password protected flash drives. I keep nothing of value on any of my machines (Main Hard Drives).
Truecrypt for first 5 (except flash drives, which are for convenience) on laptop. Encrypted home directory on the less important netbook. Jelly Bean FDE on phablet. None on iPod Touch, Kindle, or PSP. None for email (nothing worth protecting from providers or the government yet), but included plenty other security like 2-factor authentication. Sometimes I wonder why I bothered for the first 3 devices, but it's not particularly inconvenient for the added privacy (after setup).
No need to encrypt anything here. But given the current onslaught of hackers on corporate info, I can understand why these tools are necessary.
System Encryption with McAfee Endpoint Encryption. PC is company owned, not mine. To protect some sensitive personal files I use either 7Zip or AxCrypt. For Passwords I use Keepass and Lastpass (this with 2-factor auth.) No email encryption.
No encryption. I take some pains to make sure that what I keep on my computer is of no value to thieves.
I ALWAYS use FDE if it's available. For this I use TrueCrypt on windows and LUKS on linux. Windows 8 I have to use BestCrypt as truecrypt doesn't work with GPT yet and I don't trust bitlocker. I use LUKS on flash drives (sometimes truecrypt if I need windows to view it too). I use GPG to sign all emails and encrypt emails to some contacts. I use RedPhone for encryped VOIP and Text Secure for encrypted SMS. I use a VPN from my phone to my home network for encrypted internet. Yes I may just love encryption
