I've purchased myself a Mac Book Pro Retina (Haswell) and after giving Mac OS a fair shake have decided to go full Windows 7 and Bootcamp. There is no Mac OS install left on this system.

I am now looking for a way to encrypt my entire hard drive. My requirements are simple:

* AES based whole disk encryption (to take advantage of AES-NI)
* Ability to boot by just entering a password

I've looked at the following:

* **Truecrypt** is a no-go because it is not recommended for use with SSDs
* **Bitlocker** is a no-go because there is no TPM in this system and I
don't want to haul around a USB thumb drive with me every time I have
to boot.
* **Symantec Whole Disk Encryption** appears to meet all of my requirements

Before I drop $100 on Symantec I figured I'd ask the exerts if there is any other software out there I can use. I prefer Open Source but understand that might not be possible.
