I plan on installing Windows 8 Enterprise on my current laptop (it's an older laptop, but I just got an SSD drive for it. It's a Dell Inspiron 1564)
On my current Windows 7 build, I have whole drive encryption using TrueCrypt. I really like TrueCrypt but they don't officially support Windows 8 (their forums mention various ways people got it working on Win8 but I'd rather use something supported)
My laptop won't be joined to Active Directory in any way, I have never used BitLocker and not sure if that is a good option or not, or what else I should consider.
